I don't think this site has been mentioned anywhere on this site so far, so I'll post about it.
http://www.p2p-revolution.comThis is a hash database site to get around fake files. Users submit hash codes of real files to the database, so others can find these hashes later.
You can go there and search for whatever you want. The site will give you a list of what it found. The files there are rated, so you will know if the file is good or not.
The more you use this site, the more you encourage the site makers to maintain the site. If you have a lot of good files shared, I beg you to submit your filelist to the database, so it can grow.
You'll find more info about how to search and submit files on the site, so please, give it a try, so we can eliminate those fake file sharers
