Thanks for all the replies. See I am not new in that space and that scamers and spamers join groups with maybe 20 users, I totally get. But joining with 10k+ users into a 1k community seems even for the dumbest scamers a bit overkill to me. our bot bans them all if they do not pass captcha, which none of them does so our group is not growing but man, at times there are 20 captchas pending, making communicating in the group impossible and closing it for good is annoying as we have organic users (5 to 20) a day coming in and everyone lost, is for us as a project a loss.
