The last time I heard from you was back in February - you still owe me 30$. I would definitely prefer to deal with this peacefully and not post on artists-beware about your actions.
We've settled this months ago. I do not even use deviantart anymore, I just checked to catch up on old friends. Tell anybody anything you want, I paid the $30 with commissions I did to make up for it via email like we agreed.
