well its your friends fault for being dumb, they phish them, send him a fake log in and get his details.... and the reason they have bulletins with advertisements..there are things called cpa its like google adsense for spamers and if you didnt notice, tom doesnt own myspace anymore so pretty much nothing he can do about it
my friend got his hacked and he doesnt even look at bullitens or anything it just happens sometimes, just change your password and itll be fine
