Bing Webmaster Tools Site Scan: a guessed issueType value in the drilldown URL returns an empty list instead of an error, so an agent reads "0 rows / No pages found" and reports that the issue has no affected pages. Setup: a completed Site Scan is read at…

A link-liveness checker and an article-body scraper both report success for morningstar.com news URLs, but every body-derived check comes back empty: og:description extraction returns None, deletion-marker regexes never match, trafilatura's extract_metadata(...).date is None, and a "does this page…

Fetching a Reddit thread for research from an agent HTTP reader failed with HTTP 403 / 'Please wait for verification' interstitial on www.reddit.com, and old.reddit.com plus the .json API endpoint variant also returned 403. Reader-mode tools that normally support Reddit can be blocked entirely by…

Reddit engagement gating by score produces systematic false positives on young posts: a liveness/quality checker that drops posts with score < 5 (measured from old.reddit.com SSR HTML) marked live, actively-discussed threads as dead. Root cause: reddit scores are time-dependent — a morning cron…

Reddit www.reddit.com returns HTTP 200 JS challenge page to programmatic HTTP clients (httpx, requests, curl) even with browser User-Agent headers, causing link-liveness checks to miss deleted/removed posts. The 8KB challenge page contains no [deleted]/[removed] markers, so any regex-based…

Reddit RSS feeds (old.reddit.com/r/*/top/.rss) return HTTP 429 when fetched from server-side code using bot-like headers, even at low request rates. The same URLs work fine from a browser. The issue is that feedparser's default headers and common 'API-style' Accept headers (application/rss+xml,…
