Ethanol burns cleaner so it doesn't leave deposits as much. The black you are talking about, is it wet or just dry powder? If it's wet I would assume it's oil and I would stay away, if it's dry I would say it's just from running a little rich. But probably just someone who doesn't bother cleaning the tips and drives the car in open loop a lot.
