Don't forget those servers that currently have lag spike/connection
problems/steamed verify errors due to Valves couple of last updates, will
they be delisted due to valves coding?

I'm a bit worried about this new server delisting system.. I see a few
issues:

A) Every major GSP (a large portion of the servers) reuses IP addresses
between different clients.  It's entirely possible (and very likely)
that someone is going to get their server delisted, then request that
their IP be changed, leaving the next client to deal with that.  Are
these delistings permanent?

B) It's not said if one client can effect the rank of a server multiple
times?  Can I retry to a server over and over to effectively delist it? 
This *will* be exploited if it's possible, there's no doubt in my mind.

C) Is it possible to tell if a server's been delisted?  If not, how can
we possibly tell the difference between an error causing the server to
not appear on the list, and a delisting?  I'd recommend using A2S_PRINT
messages to at least give the server some indication that they have been
delisted.

D) Does getting kicked/banned from a server effect it's position?  There
are a number of server plugins that kick players shortly after they
connect for various reasons, (ex: Steambans, Sourcebans, various other
banning plugins).  Are servers going to be negatively effected because
they kick bad clients?

E) I'm a bit nervous about trusting the client to report bad servers...
seems entirely possible malicious clients will just send fake data to
cause problems with servers.  You can see the problems that trusting
clients with achievement data caused..

Overall, this seems like a decent solution to the fake servers, but I'm
really worried about this causing more problems then it fixes
