So, after a bit of playing with "person X", not using a name just an example, I decided that I did not want him being able to contact me anymore in game. So I added him to my ignore list. "Person X" then decides to get on an alt to bother me. I add the alt to my squelch, til eventually I added them all. He deletes 1 alt and rerolls, so as the character is deleted, it is removed from my ignore list, then starts contacting me again. I add him to squelch again. He does it again. I squelch and submit a ticket about it.

Now today he jumps on an alternate account and tried it some more under newer names. I submitted a ticket about it again.

Is there any absolute way that I can just block this guy forever?

Is there any other steps that I must do?
Perhaps did I submit the ticket incorrectly, using the wrong tags?
If these 2, can you explain which tags I must submit a ticket under?

It's annoying how easy it is for someone to get around the ignore list just to grief me. I've told others that will talk to him that I just want him to leave me alone.
