I just installed Kazaa Lite 2, and decided to see what the "helper" would do. (I d/l both from
www.k-lite.tk)
I went from 0 to 1000 in less than 1 minute. That's the fastest promotion I ever got, slimeball to "Supreme Being" in less than a minute.
Don't know if I will continue to use it or not.
I agree that P2P users (who can) should share. If no one shared, the system could not work. There are those that can not share due to corporate firewalls.
Merely sharing does not not increase your "points", folks have to download from you. This seems to encourage sharing (more) popular files. However, when more share the same file the chance that someone will download it from you goes down.
The system is not very well thought out, unless the client plus the cheater is just a way to edge out other (non-Kazaa) clients.
