I noticed a few people that are in my Ignore List used a Name Change Pass, and as a result of that, they got "unignored".
With this, I mean that their old username is still ignored, but not the player itself.
Let's say the player Fat-Snipe is in my ignore list.
He then changes name to Skinny-Snipe.
He is now able to chat with me, but even if he went from Fat to Skinny I would still love not to talk to this person.
If I go check my Ignore List, his old username Fat-Snipe is still there.
BUT, the new username (Skinny-Snipe) is not.
So I come to the conclusion that, unlike Friends List, the Ignore List is based on usernames rather than users.
Pretty sure it's unintended behavior.
And if it's not, one the best features of the game (Ignore List) has a big flaw.
Cheers.
I wonder if someone changes their name to one on your ignore list, will they unintendedly get ignored?
