@bobsal u1553115,
It is very unlikely that either ColdJoint or Gungasnake (who are in fact two different people) were the person who sent nasty PMs to izzythepush. It's not their style.
I do not have any knowledge as to who did do it (although I'd like to state that it wasn't me either). Considering how izzythepush spouts terrible lies about people though, I'm not sure how he has much cause to complain. Whoever it is that is doing it, I bet izzythepush attacked that person first, and attacked them just as severely as they are now attacking him back.
