Not sure why this is being downvoted. Deleting posts via scripts gave my Facebook a second life. I just use it for messenger and events. Highly recommended.

Exactly, and I put a cover picture explaining the situation (it is a closed account blabla), so I didn't receive any judgement from friends. Having removed friends, also means I can not go back in a smooth manner. It is a good way to cut yourself off of facebook's network effect without losing access to events, fb signin, messenger.

If I absolutely wanted to, I could createa second account for that with none of my friends read: um... family, that my first account had on it.

Can you link to such scripts?

If I wanted to ever use Facebook again, which I don't. I'd create a new account.
