I mean there's proof, I saw the admin's post with links. I just don't care to dig in this "drama" as you put it. .art admin I trust way more than the guy who fabricated some screenshots.
Believe who you want. It's just I choose to believe the more trustworthy person. And no, I don't want to "do my own research", because I simply don't know either of those people, or care about either of those instances.
In the end, their house, their rules. There's nothing ridiculous about it.
