I have just checked weekly voting statistic and it seems that some people where able to vote more than 40 times.
How is this even possible, since (at least in USA) week started today?
Does this depend on time zone?
Yeah, good catch, our top voters filter on the users page was not filtering out votes other than up and down.
One way this is possible is when people have multiple accounts and we merge them.
Should not be particularly common, though.
