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 of better yet,let him ask them.

I don't know

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

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

donno

idk maybe u should contact Fanpop if u 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 u should ask him what he thinks he's done.
u might as well contact one of the F4 and ask them to give him his profiel back. He might be able to get his original profiel back that way.
