When I flag posts from several years ago, the flag seems to be never reviewed, unlike recent posts which can reviewed within minutes. I have >10 case like things with flagging things written more than 2 years ago.
Why don't such flags get reviewed as fast as recent posts? They always last for months.
Note: I've read This question, but it doesn't address the difference for old posts vs recent posts. Moreover, if this answer about flag expiry get implemented, flagging old posts would mean such flags can not get reviewed.
Update
Ok, there is no common share about the correlation of a several years old post with less than 1000 view tend to not get it's flags reviewed.
I will create a query on data.SE for this.
