Dude, did you read other posts in this thread? OP and his friends were banned for plagiarism, it's not problem with evil IP or something similiar.
Yes, I read them and there is 1 example of copy-paste.
As I understand when a lot of similar activities and/or spam comes from certain IP - it becomes evil and that's the reason why "friends" can't register again
But in this case, if somebody wants to rethink behavior and be good member of forum - it seems paying fee is the best option
