(They don’t seem to do anything beyond gather some followers from her… maybe they’re DMing those followers through)
(I have the same experience with my dupes, except I’m not active, though I am more active than my dupes)
I once tried to create a new account with my real name in order to maintain Facebook Business Manager without using my private account. The new account was immediately locked until I added a phone number. I added my business number, which was immediately rejected. I added my personal number which immediately resulted in my private account being locked instead.
So I gave up and don’t use Facebook for my business.
I have an alternate profile that’s also under my real name which is 10+ years old, previously used to keep a distinction between friends and family, and it works just fine.
