This is true whenever your real identity is at stake tho? Almost everyone sanitizes their views in the public so much so there's no opinion in there anymore.
There's sanitizing, and then there's writing a parody of your life that's borderline low fantasy. If the joke is that everyone involved knows it's creative fiction, and I'm just the odd one out, then so be it. But if people reading those posts think it's anything more, I'm.... worried about people.
