I've noticed a random bug to do with showing which server game you host.

A server could be a "Trouble in Terrorist Town Gmod Game" but if you list it as a "Zombie Panic Source" which has very few servers your rank appears to be quite high as you may have only 15 to 20 people on your Gmod server but as there are very few Zombie panic servers you appear to have a very popular server.

A good example of this are the people at Conjoint Gaming.

At the moment we only partially verify servers are listed with the correct game type.

Generally speaking, having your server listed with the wrong game type should be a good disincentive to changing the game type for a higher rank, however, we do have plans to implement stricter rules for enforcing game type correctness at some point in the future.

I've changed the game type to "Half Life 2" for the server you have listed above.
