Is prank calling allowed? Of course it would be with no threats of harm or anything like that.
WTF!?!? I mean seriously WTF? Since prank calling is both an annoying and illegal activity I am going to go with hell-no even if it is not expressly prohibited by the terms of service here.
However the question is really moot since unless you already have an account and it looks like this service will likely be gone soon so you will never get an account, just like everyone else whom did not have one before they started the melt down.
