Speed:
If you use speed you speed you're game clock up,to stop this all he has to do is put it so the client reads you're time if it is going faster then normal then you get i.p banned for so long.
Auto:
Make it so if anything targets the endless window the window instantly shuts down.This would also stop t-search.
D/C:
This is the most simple thing including many ways to stop it,my way and the most convinient way would be basically when the client sees something longer then the natural breaking point of text it sends the client into ''hide'' mode.All he has to do is make it so it clips the rest off instead of shutting the client off.It's barely a few lines of c++ to fix
