There is proof all over the forum in threads discussing that he/she stole the forum, there is also a ton of threads where people are complaining about other people being banned.
For proof there is this, a user from the forum posted this on a website called cashloopholes back in 2008, he has since then deleted the post, but thankfully someone from the forum took a screenshot of it at the time...
That's all I have apart from the loads of threads about it on the actual network54 forum.
I would ask others from the forum to post here (and they would) but it's a bit hard since I'm banned, for no reason at all.
The forum is totally unusable at the moment and whoever is the owner now is just doing this for a laugh and to piss people off. Even if you were just to open up the forum again and disable his moderating powers I'm sure everyone on the forum would be more than happy with that.
