Is there any way to contact gametracker moderators becuase i have few questions about fake servers that are ranked in top20.

You can learn how to report a page here http://www.gametracker.com/forums/forum.php?site=1&thread=97181

You can find complete descriptions of every possible reason we have ever deranked or banned a server for on http://www.gametracker.com/forums/forum.php?site=1&thread=75205

If for some reason you still have an additional question after reviewing all the information provided, feel free to post here. Please keep in mind that when servers are reviewed, staff need LEGITIMATE reasons to do anything.
