They are most certainly fixing bid prices on Adwords at the very least. The 'Quality Score' algorithm allowed them to go away from an auction based system to one where they can simply increase bid prices on a whim and claim it's quality score related. You as an advertiser have no way to know what's going on.
which sends you on the quality score improving witch hunt, that leads to nowhere. Don't even think about asking customer service.... i think that even leads to lower quality score! Stop it advertiser, the more you try the worse we are going to make it for you.
until you just give up and go away...which is want the system is designed to do.
