hello, so I have this issue and have never had it before, but one of my L4D2 servers went down due to GameServers having issues with there hardware, so I re-Installed it in a new location, and I also purchased a brand new CS:S server and this is what it said immediately after I claimed it, and mind you this was a fresh install no mods even applied yet:

This server has been detected to report fake or
idle clients and it is not eligible to be ranked.

I had also noticed that the CS:S server was a recycled IP address, can someone please fix this so my servers can be ranked.. my other 2 have been ranking no problem, but these two are fresh and have no reason for not being tracked........

These are the new servers that haven't been getting ranked.
63.208.142.129:27015
209.247.83.54:27015
