GroupShield — a scam guardian for Telegram groups

Fake airdrop links at 3am. A "support agent" nobody has ever seen. A fake admin twin telling your members to DM him. By the time a real admin wakes up, a member has already connected their wallet to a drainer.

GroupShield is the night watchman. Add @NenzyBrownAssistantBot to your group and it scans every message against the pattern engine behind ScamOrNot — fake claims, drainer bait, impersonated support, fee-to-unlock tricks — and calls the scam out in the chat, in plain English, the moment it lands.

What it catches

Fake airdrops and "connect your wallet to claim" drainer bait
Impersonated admins, support desks and exchange staff
Advance-fee, doubling and guaranteed-return scams
Lookalike brand domains, risky TLDs and hidden-destination links
Links from members who joined less than 24 hours ago

Warn-first, always

Free groups are warn-only: the bot names the scam in public and deletes nothing — your admins stay in control. It ignores other bots, never acts in DMs or channels, and rate-limits its own warnings so it never becomes the spam.

Free — 1 group

Full pattern scanning, public warnings, new-joiner link checks, strike log and stats. Admins type /shield in the group for settings.

Pro — $9 / group / month

Adds delete-mode (scam messages removed, not just flagged), cover for additional groups, and priority pattern updates. Paid in USDC on Base; activate with /shieldpay. No auto-renew.
