Sombody is posting stuff as me how do i stop that?

Question

they are posting comments and bullitens on my myspace

Answer 1

change your passwords and make them real long passwords

Answer 2

If you share a computer with others, you might have failed to sign out from Yahoo at some point.  Someone else could have then got on the computer and decided to post stuff perhaps to annoy you.  This can happen when people use school computers or public computers at the library, Starbucks, even at home.  Make sure you change your password for your Yahoo account as soon as possible to prevent this from happening any longer.  

If the postings were not appropriate, see if you can delete them.  (You can delete your own messages posted on Yahoo Groups, including those in this situation.)  You could also explain to the groups that you honestly didn't post those messages if they were not appropriate.

Again, change your Yahoo password asap.

Answer 3

It depends what their posting it on but change ur password!
