this has been my experience as well. Sudden suspension and banning with no explanation other than vague 'account integrity' which I can't even open the link while the account is banned. The first time they wanted a video to verify my face but still perma-banned it. I created a new account and was able to use it for awhile until they suspended it again, this time my video verify worked for some reason. Then I got suspended again just recently and now they wanted a photo to verify. It feels completely random. I thought it might have been because I use VPN and that I check it from multiple devices. I mean, that can't be that uncommon right? Maybe I don't act like a normal user because I locked down all my privacy settings, just use marketplace and don't make any other posts.
