I picked up a permanent ban, after 15 years for saying 'Go outside fatso' to someone who said I couldnt read. Not my proudest moment, but there you go.
The reason I mention it, is that it adds a different dynamic if they are trying retain (and prevent me from editing) data which they hold about me. They might argue that doesn't extend to post where I've written "cats > dogs" - but anything where I've refered to where I live, whether I have kids, what my political views are, are all clearly personal details which they are not allowed to hold without retaining my consent.
