If I use 1 computer and 1 IP address there are many accounts that I use, but I never do spam and never break the rules, whether I'll be banned permanently?
it is not against the rule because it is also possibility that someone will have a shared internet connection like in a home wifi and a number of people from that IP will login to their accounts or sometimes people come online with their school/college or office IP and there they do not know that how many people are online on this forum.
