I've done and created a second account, which was reduced to a limited account the minute I linked my secondary phone number. Probably used that number on my old account already, so they were quick to strike it down.

I could not link a phone, but I need to link my phone number if I want to get access to more advanced functionality such as running ads, pages, et cetera.

Surely there are a thousand other ways I could sign up again -- but to be honest I don't want to jump through those hoops. I just want my account back. And since that isn't happening, I hope my tale serves as a warning for people never to rely on Facebook as they can take your access away if their bots think you're suspicious.
