how do u block someone?

Same here, I have no idea. This is what one of my Những người bạn on fanpop said.

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

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

bạn can only block someone IF that person has messaged bạn first bởi clicking on it and theres the "Block user" button at the bottom, then he/she can't make contact with bạn bởi tường hoặc 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 người hâm mộ list) and hit block they can't message you.
