StackExchange just proudly announced that I just awarded the Vox Populi badge. However, that's for voting 40 times in a day; I don't think I voted more than 2 or 3 times in a single day, ever. Did StackExchange just got a glitch?
We just deployed a change that affects the voting badges. This is why you see a number of these badges being awarded.
For more information about this change, you can see this answer.
Note that there is a bug with Vox Populi only that is awarding too many of them, beyond the expected more for retroactive awards, and a fix is being deployed now. The erroneous awards there will be cleaned up shortly.
