I would like to suggest that posts eventually become old enough that antipoints cannot be assigned to them. I just had the interesting experience of getting two antipoint assignments (probably one person) on a post over a year after I wrote it! It seems some other people were then also given negatives, and the thread committed suicide.

It was this post in the "Ennis Wanted" thread. I'm just sort of pissed because I feel like I got neg-dumped by someone going through old posts, rather than getting AP feedback for a reason.

I would also like to suggest that the Antipoint Center page shows the date when the antipoints were ASSIGNED, not just the date at which the post was made which the assignment was on.
