Just to let you know that we are dealing and exterminating; thanks for all the reports. Hope you'll understand if we don't have time to come on to all the various different threads about this right now.
I don't know a lot about how spam bots work, but maybe you could have a question like the ones for the competitions, where you have to answer a comprehension-type question based on a page that's linked to (eg the meaning of one of the acronyms). Or could a spambot cope with that?
Dh agrees that MNHQ should post the originating email addresses so we can spam them back. I am tempted to go through every thread posting, 'Oh do fuck off, there's a dear' - but I suspect that would be a total waste of time.
