Ha ha, true that. It is definitely clear to me that Meta has completely abandoned all reason when it comes to decisions about banning accounts/posts/etc. I had a room for rent ad on FB Marketplace taken down for "selling services", when they actually have a category for rooms for rent. It bewildering. I moved my ad to Flatmates and never looked back.
And that's not the only time I've been up against bizarre Meta repression that has left me scratching my head in wonder, and requesting (in vain) further detailed explanation of what crime I was supposedly committing.
