For this year's Winter Bash, the Consensus, Rapport and Harmony hats all require eight consecutive reviews where the majority of users agree with you.
However, I have seen many questions where the OP has edited their post to include more context, yet there are still 3 votes which is a majority (5 votes required to close). These questions should definitely be left open, yet choosing "Leave Open" will hinder users' chances of getting these badges.
Given the importance of the meta queues to maintaining the quality standards and order of SE sites, it is abhorrent that this behaviour has been encouraged by these hats. It is against the spirit of discouraging soul-selling for hats.
So could this trigger not be reused for future years? At the very least, it would be better to remove the consecutive part and increase the number of reviews so that one review does not affect the chances of getting the streak.
