Are selling keyloggers! PS/2 and USB for £34 and $50 respectively, although that may not be the best word to use... Look for "Thumbs Up Key Shark- Logs all character inputs." They even offer you insurance for it - in case you can't get it back?
Whatever is this world coming to? I thought I'd have to search in the back pages of a dodgy magazine to buy such stuff to get my partner's online secret Id data, but no! Good old Amazon are happy to send me it, post free.
