…Are we talking posting things anonymously or posting things with your irl name and photo?

Which in turn decreases the likelihood of something happening. Like locking a door.
The saying “If somebody wants to get in they will.” is a terrible one when left as is.

My rule is, never post anything you wouldn’t mind the media tracing back to you IRL and then making the top story of the day in your country.

So don’t live, basically.
Or you can just maintain anonymity as best as you reasonably can and hope no one goes out of their way to identify you or the account(s). Making a new account after awhile is a safe practice. The goal is to decrease the likelihood of undesirable things, not make them impossible.
