hedwards: Is there any way that we could have really old posts just locked on their own?
If a post doesn't receive any activity for a year or two, it seems to me that it ought to be just auto-locked to spare us all the necroposting. In the case where it's an actual useful post, chances are that we've all forgotten what was in the original thread anyways and a nice new thread would help keep track.
Or if that's not good enough, it would be nice to have some indication that it's a necropost other than having to look at the relatively small grey date which is inconveniently located.
Also, friends don't let friends engage in necroposting.
I think all posts that are more than 2 years old should be locked and then deleted after 2 more years pass. There is no good reason to necro a thread that is 2 years old or older.
