What this actually means

craigslist.org's completed measurements recorded no listed activity, but some optional detector evidence was not recorded in this legacy report.

The request log recorded no cross-site hosts or catalogued tracking-related services, the cookie snapshot recorded no third-party cookie records and the fingerprint observer recorded no instrumented API events. Some optional detector evidence was not recorded in this legacy report, so whatever that check looks for is unproven here rather than shown to be absent.

Plain-Language Findings

What this visit means

Unfamiliar terms are defined in the glossary

playwright-chromium

Low signal

Bottom line: few review signals in this visit

The automated visit did not observe known third-party services, third-party cookies, or instrumented fingerprint-like calls.

The cards below translate the evidence into plain language; severity reflects fixed reference thresholds, not measured population percentiles. The request log, domain table, and methodology remain below for verification.

28 requests observed in one controlled visit.

Nothing observed

No requests matched Brave Shields filter lists

No requests matched the default filter lists of Brave Shields, the ad and tracker blocker built into the Brave browser.

Computed with Brave's own ad-block engine and default filter lists in classification mode: matched requests were not blocked by the scanner and remain in this report's observed request counts. Matching shows what Shields would target on this visit's traffic; an actual Shields visit blocks these and also prevents their follow-on requests, so this number is neither a measured block count nor the total effect.

The hand-curated service catalog separately matched 0 request rows in this visit.Show matched requests

Low signal

No change observed in the Brave-list blocking attempt

The blocking visit (the scanner configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit; application was not verified)) showed no change in the comparable metrics (third-party requests, third-party cookies and tracking-related service requests).

The blocking visit's engine directly blocked 0 requests; ad rotation, experiments, or caching between the two visits can offset or outweigh what blocking removed, which is how totals can hold steady or rise despite direct blocks. A single paired comparison can also reflect run-to-run variance (ad rotation, caching, experiments), so treat this as no observed difference for this pair of visits, not evidence that blocking removes nothing.

Signed per-metric differences between the two visits; nothing is summed across metrics.Show matched requests

Context

Privacy policy read; it made no statement this scan can check

None of the statements this scan knows how to check appear in the policy text, so nothing was compared against this visit's evidence (no catalogued tracking companies observed to check against it). That is a limit of the automated check, not a finding about the site either way.

Statements checked automatically: blanket no-cookie claims, third-party-cookie claims, and combined do-not-sell-or-share claims against advertising-pixel identifier fields. Global Privacy Control claims are never checked against request counts, which cannot show whether selling or sharing stopped.

Policy at https://www.craigslist.org/about/{seg}; 0 checkable statements matched; no catalogued tracking companies observed to check against it.

Nothing observed

No requests to major-platform domains were recorded

No requests to catalogued Google, Meta, TikTok, X, Microsoft, LinkedIn, or Pinterest domains were observed in this visit.

Major-platform domains were not observed in this single passive visit; interaction-gated requests could still load for real users.

Nothing observed

No third-party cookies observed

The automated visit did not observe third-party cookies.

This does not prove the site never uses cookies; it means this visit did not observe third-party cookies.

Nothing observed

No fingerprint-like API calls observed

The scan did not observe the instrumented high-entropy browser APIs.

This is an observation layer, not proof that fingerprinting is impossible.

Brave Shields Comparison

No blocking → Brave-list blocking delta

No blocking: 4,946msBrave-list blocking: 5,100ms

Some deltas are not comparable across these two visits and are not shown.

Other detector and causal-path deltas (each visit's own evidence still renders below): v1 never recorded detector versions, so fingerprinting and pixel deltas cannot be proven to come from matching instrumentation.
The Shields-number delta (each visit's own evidence still renders below): The two visits measured different Shields quantities (filter-list matches vs engine-blocked requests), which must never share a delta.
Fingerprinting deltas (each visit's own evidence still renders below): At least one visit did not complete the fingerprint measurement, so no exact cross-visit delta is shown.
Ad-pixel deltas (each visit's own evidence still renders below): At least one visit did not complete the pixel measurement, so no exact cross-visit delta is shown.

Measurement limits

7 conditions affect how this evidence reads

This report

Brave-list blocking comparison runs should be collected under matched crawl conditions, and the blocking run is a simulation with Brave's engine and default lists in this scanner's browser, not a live Brave visit. Differences can still reflect timing, experiments, cache state, consent state, or bot detection.
The two visits ran in randomized order; the "Brave-list blocking" visit ran first.

Both visits

Each visit in this report is one automated, headless Chromium visit from a fixed en-US / UTC profile, with no scrolling, clicking, or consent interaction. Sites can behave differently for real users, browsers, regions, accounts, or network locations.
Counts are a lower bound: trackers that load only after interaction or consent are not observed; Service Workers are blocked, and Web Worker or WebSocket traffic may be incomplete. Service labels use a US-biased hand-curated catalog, so regional services may be under-labeled. Cookie and storage figures are an end-of-visit snapshot, with storage keys read from the top frame only.
This scan typed a synthetic test value into 1 form field with native form submission blocked. Focus, input and blur handlers may run and send requests. The value is synthetic and is not stored. Observed requests during typing and the following wait are included in the request log. Teardown-only transmissions are not measured.
Read the site's privacy policy (https://www.craigslist.org/about/{seg}) and compared its text against this visit's observed behavior. Policy checks are an automated text match with the matched sentences quoted, not a legal reading.

Brave-list blocking visit only

Brave Shields block simulation was enabled; matching requests were aborted before loading and are not included in request totals.

How to use this report

Read the findings and measurement limits first, then inspect the evidence for each recorded visit. Comparisons include both visits, even where a difference cannot be interpreted.

Keep this PDF with its evidence package: the source JSON, correction context, export receipt and SHA256SUMS. The package preserves source bytes and the correction context at export time. Hashes check file consistency; they do not establish independent measurement accuracy or a signed attestation.

Request attribution map

Which actor each third-party request is attributed to, from the initiator the browser reported. Attribution, not causation: an initiator may itself have been told what to fetch, and requests with no reported initiator are not distinguished from ones fetched from several. Asterisks mark subdomain labels hidden for privacy.

Attributed requests: 0
Not attributable: 0
Third-party requests: 0

No third-party requests were recorded, so attribution coverage is not applicable.

No retained third-party request has one recorded actor to draw. This is not evidence that no actor was involved: the visit may have reported no actor or several actors for the same request.

Automated Chromium scan using Playwright 1.62.1 from github-actions-ubuntu with browser 151.0.7922.34, timezone UTC, locale en-US, the listed viewport, and Brave Shields classification only. Brave-list matching uses each route-evaluated request's initiating document (the parent document for a subframe navigation), under methodology shields-request-context-v2-adblock-rust-0.13.2-request-method-v1-playwright-1.62.1+subject-validity-v3+detector-coverage-v2; main-frame navigations are not blocked or counted as matches, and redirect follow-up URLs that Playwright does not re-route are not independently evaluated. Treat results as reproducible evidence for this scan configuration, not a universal claim about all visitors.

Recorded provenance is self-reported measurement metadata, not a cryptographic attestation. The public versioned report JSON contains the retained public evidence; see the methodology for interpretation and retention limits.

This report covers what the scanner measures, not everything a site can do. 16 browser surfaces are not instrumented at all (Every page except the one that was scanned; Anything that only loads after scrolling or interaction; Why a request happened, as a causal chain; and 13 others), 3 capabilities are declined by policy, and 3 are outside what any single visit can see. Their absence from this report is not evidence that they did not occur. Read the published coverage boundary.

Detector accuracy is unmeasured. No calibration study currently publishes a precision or recall for the detectors on this page, so a detector match here is a recorded observation, not a calibrated classification. How detector accuracy is measured.

Approved use boundary: This report is investigative evidence that requires independent corroboration. It is not a standalone legal determination and not the sole exhibit in a legal proceeding. Recorded in this project's release manifest on 2026-08-02.
