What's the best way to prevent spam bots from joining a public Telegram group?

I think the best approach is using a few simple layers rather than making the group too complicated. I think one major thing that works well is enabling join requests if the group is getting a lot of spam. It adds a small filter without affecting real members. What I learned through my experience is that a simple verification system, a good moderation bot and active admins handle many bot problems.

I've found the most effective approach is enabling capcha or account age verification, using an anti-spam bot, and limiting new members' permissions for the first 24 hours, which blocks most bots without frustrating genuine users.

I think monitoring unusual signup patterns works well. Sudden spikes or repeated behavior can help identify bot activity.

the biggest challenge is stopping bots while keeping the joining process simple for real users
