You're probably seeing fake files.
If you're searching for music files, use the All Types search & search for artist or album rather than song title. Go for a file with 10 sources or less...stay away from the files with huge numbers of sources.
If you're searching for video files,
Always check the file with Bitzi before download. If a file has heaps of sources but no Bitzi rating, chances are it's a fake.
Check out the threads below for more info & tips, including how to use Bitzi.
