Yeah I'd let a mod know about it so they can check the IP addresses and origin of each message sent! 

I'd like to keep this a low profile though so I can't send you the link, it's one of the roleplays I recently joined and I don't want to accuse until I've gotten more evidence (aka, the person starts using his other account and acting like an ass again). 

Your input was valuable and it really helps. :) Btw is that a yugioh card in your icon? I remember something like it!
