Yep, its me on this thread - again.
Just a reminder to people freaking out about blacklisted individuals changing names, SE has addressed this. If you go to the player help menu from in game, they have addressed that players who are on your blacklist that change names, will have his/her name changed on the blacklist as well, and will stay on your black list.

It's just...ya know, not possible to even do this without a name change service to begin with :']
