Abusing a bug/glitch

This player (PurpleRoyalQueen and PrincessRoyal) was abusing some bug/glitch in the arena where she purposefully DCed the entire arena just because someone in here was using debuffs on her. She claims that the fact the bug exists is not her fault (which it is not), but the fact that she is abusing the bug is in fact, her fault and is against the rules. The 3rd screenshot is me logging back in after I, along with everyone in the arena at that time, had experienced the DC

Edit: She (SunPrincess) also seems to think it's okay to continue to use it and that she will bare no consequences.

It has already been taken care of. Thank you for reporting.
