Nope, no I didn't. I saw bunch of players who, after being suspended, admitted to using bots and were allowed to return. At least from what I saw on the forums, though I don't frequent them. I'm just asking based on what I know and have seen on my server.

Another issue is the obvious multiple accounts... when you have five players named Max1 - Max5 all in the same alliance, all who spam world chat...

I've never heard of anyone getting banned, but maybe I'm missing something. I still see that the filters and things they have set up are not working.
