Hi i am community moderator at Polkadot, Polkadot+ and Kusama discord servers. My fellow community moderator has made a cross chain bann bot ,which means that, if an account is banned on one of the 4 servers (Acala discord server as well), the account is als banned on the other servers. Additionally he has added a function that a ban can also be applied to accounts no longer online. I have gone through the testing of the bot with him and he put a lot of time into coding and getting this bot running properly.
The safety of our community has benefitted a lot from his input, and it also reduced the work we have as moderators to keep our servers clean.
For your information: I sometimes have to ban 25 accounts a day, and now because of this awesome bot, i dont have to do it x3 on the other servers, because it automatically gets done for me there.
Scammers tend to roam about all servers to do their nasty tricks
