Hi Striker. We appreciate the feedback. At times when you need an admin feel free to use the shoutbox on the front of our forums - if there is someone online but not in game they will jump in.
There are times when you cant see an FH tag but there might be an admin online speccing players.
With regard to "suspect" players, if you notice one and want a demo to be reviewed please feel free to post in our forums. We take the time to review the demos and discuss them between the admins. We will only ban when we are 100% sure that someone is in fact using a cheat.
One of the players you mention has had several demos submitted, and we can confirm that having reviewed them that our decision is for them to continue to play on the servers as there is no evidence that they are cheating.
Sometimes what you think is dodgy behaviour on the server is easily explained with knowledge of the map, sound, and a bit of recon by fire looking for hit markers.
