AnonSayProBot — anonymous group post bot for Telegram

Try it: @AnonSayProBot · tg.zovo.one/bots/anonsay/

What it does

AnonSayProBot lets anyone in a group send a message that posts as "Anonymous" instead of under their own name. Send /anon with your text, and the bot deletes your original message and reposts it under the group's anonymous prefix. Admins keep a safety valve: replying to an anonymous post with /reveal DMs them a hashed identifier and first name for that sender, and /ban silently blocks a sender's future anonymous posts. Free tier: 20 anonymous posts a day per group, 10 per hour per person, 500 characters max. Pro adds unlimited posts and a custom alias.

Use it without adding the bot

Type @AnonSayProBot in any Telegram chat, even one the bot has never been added to. It answers with a pitch card — posting anonymously into a chat the bot isn't a member of isn't something it can do, so this one's a pitch rather than a live answer.

Both Inline Mode and Guest Chat Mode need to be turned on for the bot in @BotFather (Bot Settings → Mode Settings) — turn Inline Mode on first, then Guest Chat Mode. Without both, only the classic @Bot query inline surface works.

Self-host

pnpm i
wrangler secret put BOT_TOKEN
wrangler secret put WEBHOOK_SECRET
wrangler deploy
curl -G "https://api.telegram.org/bot$BOT_TOKEN/setWebhook" \
  --data-urlencode "url=https://<your-worker>.workers.dev/webhook" \
  --data-urlencode "secret_token=$WEBHOOK_SECRET" \
  --data-urlencode 'allowed_updates=["message","callback_query","guest_message","inline_query","chosen_inline_result"]'

The bot needs admin rights with delete permission in a group to keep posts anonymous.
