Shieldy — is the best solution in Telegram to fight annoying spammers. It asks newcomers to execute a set action within a set period, otherwise it kicks them. That's all. Also it's completely free and open source.
Was very excited to find this bot initially, it was super easy to make it work, but then it started to scare our new users in a public chat that he'll "kick them out" if the wouldn't respond in 60 sec... I was trying to find how to change the message, but no luck. This message doesn't sound friendly at all, so have to delete it now and keep looking for alternatives.
Pros:A good way to stop spam bots
Cons:Very rude message that turns down all new and existing users without an option to change it
This seems like something I could use.
Pros:Free and nice Interface
Cons:Easy to
