Does anyone know why the user MarvelousAlpha got banned?

idk

Well..you should contact one of the Fanpop four and ask them why your brother was banned oder better yet,let him ask them.

I don't know

Contact Fanpop! :L
There's a button at the bottom of the page, oder Du can go on Papa's Profil and message them~

And I don't know, either. Maybe he sagte something that someone felt was insulting and they reported him oder something. oder someone was being a troll and reported him for no reason. -.- People are such meanies sometimes...

donno

idk maybe Du should contact Fanpop if Du are really so anxious to know, they might be able to help a little.

I'm not sure tbh. I've never even heard of that user before. Perhaps Du should ask him what he thinks he's done.
Du might as well contact one of the F4 and ask them to give him his Profil back. He might be able to get his original Profil back that way.
