Plumbline

Changelog

Detector and wording changes are listed because they change what a verdict means.

2026-10-22 · Sharing and guides

  • /share opens Telegram's share sheet with the bot link; nothing about the sender is tracked.
  • Three guides on the site: fake Telegram support accounts, seed phrase and wallet-connect traps, and how to check a link by hand.

2026-10-21 · Trust and transparency

  • Telegram links are now judged by handle: look-alike and impersonating handles, bots, invite links, proxies, invoices and share links, tg:// links and bare @handle input.
  • Every result lists the checks that ran and the ones that could not, with the time.
  • A "Wrong result?" button sends a note to the maintainer; confirmed mistakes go to the public corrections log.
  • /about shows the blocklist size and age. The site has a live status page.
  • /deletemydata and payments return itemised receipts; /paysupport lists your payments.
  • Wallet checks show a progress message and edit the answer in.
  • Detectors measured against a curated set of 288 legitimate sites and 386 generated look-alikes (see Accuracy). Fixes found by that test: brand names in front of another domain, short brand names next to words like "claim", digit and i/l look-alikes, and a false alarm on walletconnect.com.
  • 18 more brands (exchanges, wallets and DeFi sites).
  • New weekly digest and /stats for the maintainers (aggregates only).

2026-10-21 · Visual identity

  • New mark and avatar: a plumb bob over a swing scale. Messages use a level gauge, quoted observations and a collapsed detail block for Pro.
  • The bot sets its own profile photo; an empty-chat banner was added.

2026-10-21 · Launch

  • Link analysis: URL structure, look-alike brands, punycode, domain age (RDAP), redirects, page signals, blocklist (Phishing.Database).
  • Wallet analysis: address validation, state, age, activity patterns, flagged counterparties, community reports.
  • Telegram Stars billing: 7-day pass and monthly subscription, refunds, expiry notices.
  • Community reports with abuse controls, maintainer flags, Pro watchlist, inline mode, Node and Docker build.
