To be honest Dot , it was pure chance that I noticed that post. I am learning to drive just now so decided to have a nosey in motoring and as I said on the other thread , it was the fishwife reference which caught my eye and made me smell a rat. I didn't think you would refer to yourself like that but I must admit , I had my doubts when they answered saying that you had to keep changing your name. I didn't know what your other IDs were but remembered seeing you post under similar names and thought that maybe you were just messing about in this post and had perhaps been temp. banned due to overposting. It seemed like a reasonable explanation until the real you showed up ! I don't know why you seem to be the target for imposters all the time , it really is odd.
In answer to your question PB , I have only ever been the same name in the few years i've been on AB. I don't see the need for constant name changing personally although I know of a few who have changed names because they were getting a rough time on here and wanted a fresh start. There seems to be certain ABers who have various IDs just to wind up others , either in malice or in jest. Then there are those who keep 'backup IDs' in case they get banned.
