Just save that for future use. You might want to keep a copy on your phone. Then when you get invited to the party, have it ready for use. Play it and then leave the party, block em, and report. I did that to one squeaker who had his buddy send me a message on xbl. I replied with the same, reported and blocked. Remarkably they tried one more time. I repeated and left a message that the OP's tears tasted so sweet...then before they could reply I blocked them too. To think this kid had not one, but TWO friends! LOL!
