I was going through my favs and just found out that everything from SitriAbyss is gone and their account is deactivated. Any idea what happened? The patreon is still active and links to here. Thinking back, I don't remember any mention of trouble or potentially shutting down their page on here. Since you've done tributes and trades with them, I thought you might be able to contact them and find out what's going on.
Yea Sitri is a new victim of the DevArt Bann Hammer. Some assholes reported his work here and DevArt Admins don't look if it is correct banned him immediately. That can happen to any artist here who shows slightly sexual content on DevArt, no matter if it is against the DevArt Rules or not.
And I know Sitri's Stuff. His work is like mine, but he never broke any rules, but he got permanetly banned. But he is fighting and in contact with DevArt about his page here.
Since I have no way to contact him, if you could, please pass on my support and a potential new home should his ban stay in place. Slushe.com is specifically for erotic 3d art so you and him would fit perfectly if devart becomes the next tumblr and purges anything with nudity. Devart doesn't realize they'd lose a good portion of users if they do continue down this path so I hope they allow him and other victims back.
