Best guess, based off the vote count differences of those two days, is that if you see a vote with 100,000 count, it's likely closer to 20,000 count (divide by roughly 5 or so).
There was a post about it by KeyserSosa on Dec 6, so it's not some conspiracy or anything.
Yep I remember. Its an estimate...kinda. there were many reasons given but at the time it felt bad. Like they were trying to hide the counts...which I still think they do.
I think the given reason was to prevent vote manipulation by fuzzing the counts or something like that, but I always to took it as the admins and supermods cherry pick which posts they want to promote and alter the counts, so basically pushing certain messages and politicking.
