No you don't (officially), I also use a throwaway account and had no issues. There were a few unrelated isolated incidents in the beginning that were heavily publicized by the media but in the end you're at the mercy of the same AI ban bots just like with YouTube, Google or any other big platform so you have the same chance of finding yourself locked out if your behavior trips up the algorithm.
I recently created a throwaway FB account for "work stuff", and the amount of spam mail I'm getting now each day from Facebook to "engage" is shocking. Also: I didn't register the account with my real name and a different email address, yet Facebook magically featured out who I am and is sending out invites to the friends on my (long dead) real Facebook account. It's all creepy AF.
