I’m not saying don’t delete your account - I still don’t have one, but be aware that it may not be as simple as just creating a new one if you change your mind in the future.
This is exactly what happened to me as well.
Subsequent attempts to make new ones were instantly banned for “no reason.”
They did work with me to reinstate the 2015 account. And it’s never been banned or suspended since. I don’t really use it anyway.
But that’s how they are. They trust older accounts. New ones are treated like criminals.
So to them, “this is the profile we’ve decided is amy “ and “this one isn’t.” Even if it is….
I think it makes sense to allow reuse of usernames, but only after a sufficiently long period of time. I don't know if 20 years is enough, but something in that ballpark would be needed to reduce the risk of identity theft.
For all the bots that clearly get through, they have some pretty onerous algorithms at work to figure out if you’ve ever had another account. It seems to matter not whether you use a different email or IP address. The same name alone seemed to be enough for them to lock a business account I was trying to create.
They’ve gotten a LOT more aggressive I think. About 12 years ago I created a second account in my own name for use exclusively with family, and never had issues with that one. I think that part of their risk analysis is that whatever risk analysis was performed at the time the account was created is somewhat sticky. Likely to prevent complaints about changing goalposts.
Of course I don’t use any Facebook/Meta property anymore.
