Bovski we were discussing reliability of the sources. In my opinion we should remove support for unreliable and not worthy sources as:
fulldls.com any bs keyword returns results
TorrentReactor.com rerurns results on any search, pick up any string and it will return torrent for it
SumoTorrent.com lies about peers numbers, offers many dead torrents, generally useless.
Not for removal but also worth mentioning:
limetorrents.com returns fake amount of seeds/peers
isohunt.to returns fake amount of seeds/peers
Biggest problem that search engines filters are reset after each script update.
I don't have problem with removing sites that give bad results but the amount of seeds/peers can be difficult to monitor with the amount of people using DHT you cant just ask a tracker as you did in years past so you can't really penalise sites for that.
I normally only do scripts that are requested so assume they are of some use.
