I distrust OctoEverywhere after they gave me the runaround for three months of trying to cancel my paid account. They kept charging me, telling me they were sending me a refund, but never did. It didn't stop until I replaced the credit card. They were always polite and apologetic ... and then did nothing.
This isn't evidence that they messed with usage stats, just that from me they get a little less benefit of the doubt.
