im not sure which method of "hacking" these people used, but i have seen the KAC module catch people all the time. However, there is one method that i think KAC cannot catch. This method seems to be the most simplistic of them all and open to any dummy css modder out there.
don’t think il post how to do this due to the amount of people that may try it, but maybe i should talk to you sio, then again you probably already know.. err we might have talked about it before.
