Previously, calculating thresholds for reviewables was done based on the 50th and 85th percentile across all reviewables. However, many forum owners provided feedback that these thresholds were too easy to hit, in particular when it came to auto hiding content. The calculation has been adjusted to base the priorities on reviewables that have a minimum of 2 scores (flags). This should push the amount of flags required to hide something higher then before.
