Similar to what was discussed here, I've implemented preventative measures on replying to posts that have been dead longer than 21 days.
Stickied threads, Mods, Admins and Extractors are exempt from this restriction. Certain entire forums may also become exempt from this restriction if sufficient reason is found to do so.
The range itself may be expanded, right now it's a compromise between 45 days and the 14 that a necropost normally would occur under.
The intent here is to completely do away with the necropost warning/infraction at some point. I believe strongly that the best way to enforce a rule is simply to not make it breakable in the first place thus saving both sides time and energy that can be better spent.
