Yep we have the 'Number Cruncher' group which displays no ads to the user, much faster on page load.
It is not public knowledge but it is available for those that donate, and covers both 'ps3crunch and 360crunch' sites.
So far only one person ever decided to do so.
I have been thinking of opening it up as public knowledge to cover the extra server costs from all the cfw usage has cause us to break record numbers and means we are using more cpu server rack power then before.
