Just to put my thoughts in here as I have been away for a few days.
We are all in this together - we share the same tags and are in the same community. You can choose to be pro-active about keeping the servers clean, that is your choice. You can choose to do nothing and complain, again your choice. There are no requirements of your effort for keeping the servers clean however the more you help the more will be done.
As far as the 'evidence' not being good enough. There are many hacks out there and our admins are experienced with dealing and recognising them. The majority of videos we receive are accompanied by the accusation of 'hacking' and claims that it is obvious. Now we need to know that with beyond reasonable doubt that the player is hacking, if I can put whatever we see down to a graphics glitch, network or something else then there becomes a doubt.
I kind of like the ticket idea.
