What is the deal with this Bitzi ?

I've tried using it to verify literally HUNDREDS of files that I want to download and each time it gives me the same message that:

"We're sorry, but Bitpedia has no information about the bitprint:"
Well, what the f**k does it have info about then ? Surely some of the thousands of hosts with the file I'm after got it off Limewire . . . how were they allowed to download the files ??

I realise there are jokers out there who just take the P*ss and call a file something it's not but surely all of these hosts aren't at it.
