(...) a bit surprised to see they ended up adding the green K badge to all the backers.
They didn't. I am an early KS backer and got no badge. Hell, I'm even considered a "stranger" .
The stranger rating has to do with how much you post which you don't given this is only your second post in well over a year. As for your badges I suggest emailing Larian support from the email linked to your pledge and give them the details about this forums account.
