search by username = stalking

[nocampinghere]

Why is it possible to search all historic threads by username?

Surely it only encourages stalking?

What genuine use is it for an indefinite time period?

Is it possible to block /or if not delete old posts?

I find AS useful if a poster is really unpleasant on a thread. It shows if they are just having a bad day or if they are always an arse who insults and belittles.
