Stop letting your moderators act like white knights.
I have never been harassed by something so small as an art credit on a piece of art I own on this or any other site until today. The moderator nitpicking such a thing when it was clear that I was the sole owner makes me feel as if they were bored and wanted to push their power. O can understand that it was in violation of ToS and immediately changed it, but this has literally never been brought up to me anywhere else...even on sites that may have rules as strict. The moderators are there to cease trouble and not to cause it, so why did this event even need to happen?
