I find it impossible to believe that Facebook will ban you for using Oculus but never posting anything to your Facebook account. It's such an extraordinary claim.
Part of why I personally believe it is I've seen how Facebook really doesn't want people making fake accounts. I had a Facebook account and was friends with like, 2, family members, never really used it. Somehow Facebook decided they needed to see a photo of my drivers license to let me use the account. Nope. I decided to consider this a feature, and there has been a time or two over the last several years where that persistent requirement for a drivers license to unlock my account has kept me from giving in to peer pressure. Facebook has helped me avoid using Facebook. It has been to my advantage.
I believe that it's an algorithm thing. Since you aren't acting like most people on facebook then you have tall poppy syndrome and the algo locks your account and sends you a notice to provide more evidence that you are who you say you are. Then since they basically have no customer service you either do what their AI says or your account stays locked.
There are already tons of people complaining this is happening. Headset owners create Facebook accounts which are quickly disabled. Just do a quick Google: oculus facebook ban
Technically they are not banning people on that ground. What they say is they found their accounts violating “community guidelines” or some BS, and that “this decision is final”.
If you think that’s an extraordinary claim, well, that’s the kind of behavior international users of American SNS is usually forced to go by. Since 5-10 years ago Facebook/Twitter/Google/etc all started banning people by flagged content counts and their agenda based algorithms with “violated community guidelines” types of phraseology instead of citing any particular offenses picked up or verified by human moderators.
There’s plenty of anecdotal proof if you just check the Oculus Quest subreddits. The amount of people who didn’t have Facebook accounts are probably not the majority so I guess their strategy has been to ban first and deal with all the frustrated users on a support call basis. Not a bad business decision but a shitty human decision from a moral standpoint (for whoever made the final call within Facebook)
