xyzzy - Sometimes it seems there are more 'questions' posted about how many questions about tyre pressures are posted, than there are questions about tyre pressures.
FYI: There have been four questions about Artex since 1 January, and four posts from people complaining about how many questions about Artex there are. (Every time you post questions like this, it gives Google another reason to direct inquiries to this site).
Other random searches on Google that bring this site as top or near-top matches include (this morning): "animals beginning with n", "dale winton married", "lynx advert music" and ... you get the picture. No conspiracy.
On a different tack, assuming you are right and there is a single person creating all these Answerbank accounts in order to post questions about Dale and Nell... surely you are playing into their hands by getting so worked up? Why not ignore the questions you don't want to answer and let other people get on with them. Please?
