I think this "unhealthy client" is currently a totally non-issue.

Gnutella never really had a problem with unhealthy servents in the past or today. Of course the protocol has is weakness and software is never bugfree, so are programmers. But if someone speaks about unhealthy client, then it's usually a marketing phrase (some call it "Vinnie phrase"). Better ignore this topic, instead test new software, give the developers a short feedback and they will fix fast in case of problems, also create better software, improve the protocol, improve Gnutella. That is what happened with Gnutella in the past. Back to topic, a forum is a great place to share knowledge, help users and improve a client. Without communication you just hide problems, not solve it.
