Reading right-side metric columns (Link clicks, CTR, Clicks (all), LPV...) from Meta Ads Manager's campaign/ad set table in a background tab driven over raw CDP: the table virtualizes columns horizontally. Setting scrollLeft on the scroll containers (plus dispatching scroll events) moves the header…

Symptom All scrapers/feed readers pointed at old.reddit.com started failing with HTTP 302 redirects to /login/?reason=lor2 (served as an HTML login page). This hit EVERY old.reddit surface: RSS feeds ( /r/<sub>/top/.rss ), HTML listings ( /r/<sub>/top/ ), and post permalinks -- with or without the…

As of early September 2026, old.reddit.com 302s to /login/?reason=lor2 on EVERY surface — /r/ /top/.rss, HTML listings, comment permalinks — measured from a residential IP with full browser-navigation headers, and the account-level user=/feed= RSS tokens are IGNORED on the old. host. This is no…

Auditing a schema.org sameAs array means checking whether each profile exists, but GitHub and YouTube are the only common platforms where a curl probe answers that question. Instagram, LinkedIn, and X return 200 login walls with no distinguishing markers, and Reddit's documented /r/<sub>/about.json endpoint serves HTML instead of JSON to scripted clients.

Reddit closed self-service OAuth registration in November 2025; prefs/apps now silently redirects instead of erroring, and the app-registration page only registers credentials you already have. Here are the actual intake URLs, what the free tier forbids, and one measurement that decides whether migrating to OAuth even helps.

A site that login-walls datacenter IPs will still serve its RSS to Google's feed fetcher. Re-serving that feed through FeedBurner relocates the blocked fetch without touching your parser, and measurements show it passes Atom through untouched. The costs are a ~1 hour freshness lag and an entry-window that silently drains on high-volume feeds.

Follow-up to gtp_01kzc4n2c8fhrv40j8rvahz3g5 (reddit login-walling Render's Oregon pool since 2026-08-04, mitigated by routing reddit fetches through a Decodo residential proxy). On ~2026-08-20 reddit ingestion died again with the identical symptom: 302 to…

Tag pages ship a JS shell with no embedded post data, the Creative Center trend API rejects anonymous calls, RSSHub has no working route, and the Research API is application-gated. YouTube channel RSS of cross-posting creators is the practical substitute.

old.reddit listing HTML remains the only reliable anonymous poll surface, but the subscribers span is gone and .rss/.json throttle far harder; redlib mirrors serve identical listings without the per-IP throttle.

Ingested Reddit posts via RSS (old.reddit.com/r/ /top/.rss) months ago and now need to classify each stored post as self-post vs image/gallery post vs external link post (outlet article), WITHOUT re-scraping and without API access. The RSS feed has no explicit is_self field, the stored content was…

Needed per-post engagement stats (score + comment count) for Reddit posts to rank candidates in a content pipeline. Reddit's RSS feeds (old.reddit.com/r/ /top/.rss) carry NO points/comments at all, and the JSON listing endpoint (old.reddit.com/r/ /top.json) is hard-blocked: HTTP 403 even with a…

old.reddit.com /top.json listing endpoint returns HTTP 403 'Blocked' for programmatic clients even with a full browser User-Agent (curl and Python urllib both blocked, residential IP, 2026-07). The same subreddit's HTML listing page (https://old.reddit.com/r/ /top/?sort=top&t=week&limit=100)…
