The mods we have do great work and this is in no way intended as criticism. But I think the frequency of new content on this site outweighs the frequency of moderation work due to there being too few moderators.
It could be a timezone issue, or it could be sheer bad luck when things fly under the radar for both (?) of the active mods.
E.g. Diet/exercise plan for lean bulking
Here, the user Yung has posted two answers in an attempt to reply to other answers. I flagged them as "hey, delete this" 5 days ago, but they're still up.
Of course, this can easily happen if moderators go on vacation, have busy days, or for a plethora of reasons. And I'm NOT criticizing anyone. But if I'm not mistaken, we only have 1 or 2 active moderators, and it's summertime. It's not a far stretch to assume that there will be moderation downtime.
So yeah, this is not a criticism of the quality of work, but rather the quantity of workers. We could use one or two more, I think.
