Is this 100%? i dont remember restarting the router so the ip should be the same but what about internet cafe's for example, if one guy gets banned then all of the accounts that played on this internet cafe get banned too? seems weird.Thanks for the answer btw.
edit.My roomate with whom i quite frequently play with and on the same network didnt get banned, he just got demoted because they deleted around 20 games that we played together(after the ban of the old account not the new)
