Although I can tell that your upset, this isn't the right way to say that you are mad. If you have a problem with a moderator here, then send them a PM of there reason.
Being a artist myself, I know how it is when someone steals artwork and it can get very upsetting. Now I haven't seen any of the artwork personally, nor have I seen this other moderators art you are mentioning. So without really proof of this it's kinda hard to believe. Again lashing out and making a public trend about this isn't really the right way to handle it.
Also, are you talking about a moderator here or a moderator for Arokai
