Site purchases scam(ish) content from eBay (cookbooks, get rich quick stuff, how to, etc), then posts it for all to see.

Fluffy:  
I don't know what all the low votes are about here, but this is a great concept and there's a ton of highly amusing material through this site. Maybe Mac's description doesn't do it justice: they're ripping off the rip-off artists. If a scammer wants to complain, then BAM! they're not anonymous or protected anymore. Hoisting freaks on their own petard gets a 10 from me.
Fluffy: Do you want to learn the art of throwing knives?  
 
Ever wondered how it is done to perfection every time??  
 
Well here is your chance. This ebook contains well over 50 pages of detailed information and illustrations all about the art of knife throwing. This intriguing Ebook focuses on the ninja's techniques and training. This is a must for all martial artists and anyone wanting to learn the knife throwing techniques of the ninja.  
Fluffy: also:  
 
Convert your engine to run on ordinary tap water.  
 
This is not a joke! - This is easily carried out using readily available components!  
 
Suitable for all engine types, including turbocharged and supercharged - No petrol or diesel needed at all - EVER!  
 
Amazingly, your vehicle will return more miles per gallon (of tap water!) and engine power will be INCRESED by around 33%. Once again, this is no joke.  
 
This conversion was demonstrated on BBC's 'Tomorrow's World' program in 1986. The engine will run off the 66% hydrogen found in water.  
 
You can expect to travel a distance of between 50 and a theoretical 300 miles per gallon of water, depending on the set up and adjustments made. Cost of parts needed is under £100 though several hours labour time are required to fit and set up the system.  
Fluffy:  
uh, to be fair, I never tried opening any files. perhaps not recommended? that could get some low votes.
Shreela: I DL'd one: PDF and a scan of the cover. The DL rate is slow, even on dialup (sometimes less than 1kb/sec)! My cable modem is toast, so I can't comment on the speed from a faster connection.  
 
But I opened one of the PDFs already; it's very nice, and even opens in Foxit PDF reader.  
 
Thanks Mac, 10!
sobchak: true, not sure about the low votes. but then again, the '1' votes don't often make sense to me.
