Old member of illegal site what can I do?

Hey guys, I've been registered to a site that was dedicated to RS hacking and what not but I've since left and I want to become a member of Sythe and open my own store and hopefully become successful

I heard that it is bannable to even be registered to those sites so what can I do to get around this since I have left? Also is it possible to change my username?

 

Hey man, not sure about your first question, but changing usernames is not allowed
