Interesting. I've been wondering about that from time to time - every now and then when something makes it past the spam filters in fact. Two questions always pop up: 1) who actually buys this crap* (both figuratively and literally) and 2) how does the money reaches the scammers? No point in setting up such a "business" if you can't get your hands on some cash from it.
No surprise however on the most effective counter attack vector - money (either by giving or denying it) is the best weapon there is.
*Rethorical. Don't bother - we all know. Same as the teleshopping channels. Just keep an eye open at garage sales or on who brings what to the landfill.**
** "I know what's going on in the neighbourhood - I don't live next to the bottle bank for nothing!"
Bootnote: I still think it's an ill-chosen name for a conference. Come on, I can't be the only one who reads it as unisex enema at first every bloody time.
