Just like a bank does - a suggestion

[Machecoul]

Having seen all the discussions about imposters ... would it be possible to get each ABer to register some "private information" e.g. why they've chosen their screen name.

Then if someone is suspected of being an imposter they could be emailed and asked the question.

Wrong answer ... then goodbyeeee.

I do realise that this might be too complicated and too time consuming on your part to sort out / carry out.

But it's a suggestion :)
