I just ploughed through the answers I'd given to find why 6 of them had been banned. (You can do this by clicking on My Profile and then Questions I've Answered.) Turned out the system had gone haywire and filed the same post 7 times, each one with an extra word or two, until No 7 was the full post I'd submitted. The previous 6 were then banned. Fair enough, looked daft. I didn't know anything about this at the time - I think it was the AB submission system rather than my own computer that ran off the rails. So take heart, it doesn't mean you're a bad person.
