A large number of bots / airdrop hunters are joining my Discord, all with the same naming pattern. 

They all join, say "gm" and do nothing else. 

Anything I can do to stop them? Couldn't find any tools for Discord anti-abuse nor best practices.

Don’t think we want to pay for help right now, this isn’t really a big deal and we’re not at large scale atm

There’s a paid service I can connect you with if looking for professional help. 

If looking for free tools that’s cool too but can’t help

i think @taytems.eth found or built a discord bot that prevents accounts from joining the ENS server based on regex username, not sure if it’s open source

https://botbasher.humanode.io/ heard that this one works well, but haven’t tried it

based on decentralized biometric auth

Make me interim admin and I'll delete them 😈

Use collabland or guild to add some basic requirement to join. Might limit it a bit

To be perfectly honest this is my pattern in half the servers I am in 😅

We used to do a questionnaire that unlocked the rest of the server in bDAO, filtered some but can’t say it solved the problem by any means. Mandatory town hall after they join?
