In recent versions of Kazaa Lite, I have noticed an unbelievable dependency on the Blocklist feature (under Filters tab in Options). Just so that you don't miss out on important downloads (which may be listed with wrong descriptions), I would suggest cleaning the Blocklist out completely. The only things I left in my Blocklist are the "full-downloader" entries, since this is a big annoyance on Kazaa.
I cannot stress this enough, especially if you download alot of porn. All it takes is someone to slip the word "lolita" into some 19yr-old's pic description and BAM you can't find it.
