Since Start of 2011, Adbrite Revenue Significantly decreased

This is not a minor decrease either, My traffic stats are roughly the same, and on some days more, Yet my revenue has dropped over 70% of what I was getting per day.
This is such a big increase so thats why im posting here.
Has anybody else got this same problem?
I contacted them and they just told me they cant control what there advertisers bid, Which is fair enough, But there is something else going on that they are not saying
