I check my user page on old comments fairly regularly. Usually once a day to see if there have been replies or moderation.
I don't specifically recall checking it yesterday, but I think I did. Today upon checking it I noticed a slew of flamebait/troll/redundant moderation on extremely old stories that didn't seem to be previously there.
I thought slashdot turned moderation off on stories that were more than a few days old, but I certainly don't recall previously seeing the flamebait on the May 5th comment and 12 days seems to be back to the point it would have been shut off.
It might be interesting if slashdot would at least display when something was moderated, because that kind of moderation to suddenly appear on several comments at once certainly seems fishy.
