Just ignore the second account as well xD. It is literally that easy.
If this was just some other player, i might agree with you a bit, but seeing as it is cabadge, i do not agree with just putting his alt on /ignore (ignoring the fact that he is breaking at least 2 rules already).
H, Do not start personal arguments or create intentional drama between players. The staff has the right to mute those who they consider being “toxic”.
A, Do not disrespect or harass any player or staff member....
B, Do not, in any way, threaten the server or other players. This includes death threats, threats of violence, and threats of and/or carrying out a DDOS attack.
Cabadge has a well documented history of being toxic and harassing players on the server. He has already been punished (according to the staff on my last report) for targeted harassment and toxic/disruptive chat, with a warning (12/16) for "inappropriate chat" when he told someone to go get bent by a tranny whore.
He goes out of his way to start shit, breaks rules fairly often (i have witnessed him evade the filter, spam in chat, cuss out players, send disruptive chat, harass players, threaten players) and I think that he needs a good hard punishment now for targeting someone who put his main account on /ignore and threatening them via an alt account.
