how do u block someone?

Same here, I have no idea. This is what one of my friends on Fanpop said.

Go to your messages and next to the inbox/sent/trash options there is a "block users' option.
Just click on that and add the usernames of the users you want blocked. Any further PMs sent by blocked users will automatically be discarded into your trash box.
Hope this helps!

Didn't really work for me, but I guess you might figure it out, since I have a feeling you are smarter than me.

You can only block someone IF that person has messaged you first by clicking on it and theres the "Block user" button at the bottom, then he/she can't make contact with you by wall or message.

umm just go to your offline buddies try to find wait i forgot im sorry

Throw a brick at them? .3.

press the block person bottom
Baka!

2 ways
1 = go to messages and hit block users
2 = go on meebo look up the person ( if they on your fan list) and hit block they can't message you.
