If i log on to my friend's home ip only once before. after a while if his ip got banned will my account get banned?
This will be a complicated case, but if the staff are able to determine that you and your friends are two different person, you should get unbanned if you were to be banned. If you are banned, you would like to give the staff as much information as possible which can helps them to determine that you and your friends are indeed 2 different person.
