Not familiar with this particular situation except what's contained into this thread, and don't know this Artyomis guy.
...but sounds like an uber character got his feelings hurt because a GM was over zealos in his job of detecting exploits. The player pitched a fit over the mistake because his sterling reputation was tarnished. (*eyesroll).
The GD graciously apologizes in public. Yet the player is still being pouty about?!
For goodness sake, is he like 10 yrs old or something?
