I've been the beneficiary (victim?) of a slew of badge-inducing up votes recently, receiving probably five or six Nice Answer and Enlightened badges in just the past week.
The random up votes are not surprising, since I get a lot of passive rep. But it sure seems weird that a whole bunch of accepted answers that had nine up votes suddenly, one or two a day, have been ripening into badge-producing fruit.
I'm just saying. If someone is gaming the system on my behalf, please stop. I don't need or want the help.
