Go into My Profile which is on topics list (over there <<<<). And they will be on "questions I'm involved in (or worded something similar). If they've been banned they'll state that in a inky red banner across the top of them.
If your answer's were on a post which in itself has been banned or removed (ie, it got abusive etc) I'm afraid they won't be there.
I've been into all of them and none of them say anything??? I've not been abusive so if the question was it will be removed? Nne of them have disappeared so very strange. I dont usually get into the arguments that some do on here. I got on my high horse on one question posted by Ed but it's still there and I wasn't rude.
