Not necessarily aimed at VM, but ad brokers with contracts that are very one sided seem to be the rule rather than the exception, at least in my experience. I read the contracts, but only have AdSense and Kontera on the site.
VM has approached me a couple times. If I recall right they assured me they could pay more than Kontera (which I run now). But the "25% of AdSense" you mentioned wouldn't get me to switch.
The last broker who contacted me had a 30 day cancellation notice going both ways, fine, uhhh... except for the little clause elsewhere in the contract that would let them cancel immediately. Yeah, that's equal.
I can live with a 30 day contract, even 90 days (prepaid only) if I serve the ads from my server so I know whats being shown and it can't be switched without my knowledge, but not a year.
