I think the spammers are alive to most wheezes but hash codes do not seem to be in their radar - or not for small outfits anyways.

He has no problem with Macs/HTML, he knows them inside-out though he has never heard of the bug that locked-up the OS terminally when you dragged and dropped the clock into the trashcan.

But if Hashcodes are Windows specific then that is what he is reporting. Surely it would be down to the overall effect, a Windows only page (Mac users would not wander there) that allowed surfers to e-mail him would pull-in customers. He uses the jpeg wheeze and gets e-mails but maybe he could get a few more who knows.
