Today, I reviewed low quality posts. I started with 520 reviewed posts, and I ended up with 712 reviewed posts.
I checked after few hours, and the counter is now lower.
Why does that happens?
I noticed it happening twice, already. When I checked before, the reviewed posts were higher than 520.
I reviewed more low quality posts. When I stopped, the number of reviewed posts was 1194; I checked after one hour, and the number of reviewed posts went to 1150.
