I just took out 16 posts in the admin pool, and nearly all of them have been from people making necro-posts. Well before today, the vast majority of the ones I've seen are from lots of people doing the same thing and answering questions that are already fully covered. My personal favorites are the one that post on old questions and are still incorrect. :P
It's understandable why, since I know that newer users are trying to gather enough points so that they can get basic privileges like wall postings. There are always the moveset posts, but many of the new users trying to gain experience here often may not know any ways to construct solid movesets that haven't already been posted here, so it's a bit of a catch-22. I'm seeing a few core issues here I had a few ideas here that hopefully doesn't favor any group of people here much if at all:
- Lock posts like you do with the username posts so that questions can be locked once they are resolved. Should the information be inaccurate, someone can still leave comments to cite the incorrect information and then the post can be unlocked and free to be replaced with the right information.
- Provide another means to give users points in a way that helps them contribute to the site. I think the reasoning behind the point restriction is really great, but at the same time, we have a load of new users coming in with a finite number of posts. I think some of the demand for answering posts is partially driven by people trying to answer something if just to get one upvote for wall posts. It's simple enough, but I think opening up some new way of earning points would help to please that demand.
- Come up with an obligatory Simpsons reference. I haven't gotten to watch in a while, so I've got nothing. Sweet merciful crap.
- Create a mini quiz to give new users a general guide and award points for completing it. I can't be credited for this, but it's down in a few of the comments below. I think this method can work greatly for new users. My only concern are for those odd users that come up that don't use any kind of bots or programs for spamming, but still just spam the slower way. It might end up defeating the purpose of the point restriction.
