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 atau better yet,let him ask them.

I don't know

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

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

donno

idk maybe anda should contact Fanpop if anda 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 anda should ask him what he thinks he's done.
anda 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.
