No, I am not asking for help to get around IP bans LOL. Here is my dilemma. I am Moderator of a forum for a Book Fan site and I have a couple of questions about this. We have recently begun dealing with a troll and unlike most trolls, he is persistent. We banned his username and the likes but he was able to come back and make multiple usernames(in the past 2 weeks, he has made 30) so we finally IP banned him Problem Solved...or so we thought? Apparently he is able to change his IP as much as he likes so even though we IP ban him, within 5 minutes he is able to come back instantly. So he repeatedly comes back trolls and insults the members and members. There is a new user who types with similar characteristics of the Troll, I mentioned about so we have suspicions but if the troll can change his IP we don't know if it is a harmless new person/coincidence or the actual troll. Is there anything we can do to get around him changing his IP? Also, is there a way we can still tell it is him even if he has changed the IP? I had a younger brother who was a member of some game site and even though he changed the IP, somehow they could still tell he shared an IP address between user names. Any help would be appreciated.
