My friend asked me what he can do about a forum owner that banned him but would not take his threads down as he asked as they had a lot of private information. The owner caused him problems and made the forum members turn on my friend as he lied and then deleted any replies from his thread that told the true facts. It was over some small thing regarding a video my friend made for him and the forum owner would not pay him and it just got worse. What can he do about it? He now lost all his friends he made over 2 years as they all believed the owner as my friend could not post anything to defend himself.
