There is only a very small number of users who actual actively look at the review queues.
What I see happening is this:
- User posts question
- User does not read the notice about how there is a wait before the question appears
- Question does not appear on main site
- User posts the same question again
- Question still doesn't appear
- wtf is this shit? And dissapears never to be seen again
- Now there are two questions that need approval in the queue, and their OP is long gone
- Very few people actually check the queue and it takes 4-5 hours for questions to be approved
- Questions come through in huge lumps as the last vote required for approval comes through
- The front page of the site is unchanged except for when 30 questions get dumped all at once
- There is no public review process of questions that were rejected
- e.g. when a question is posted and then closed, people can see the closed questions and vote to re-open, or post a meta thread
- if a question was never even posted, then there can be no wider community involvement in disagreeing with the actions
- There are no "signposts" left behind, like staking the bodies of your enemy outside the city gates. People will never see the kinds of questions that we don't want here, and will post their own question because there's no evidence that these questions aren't allowed.
I don't think this is a very good idea. Really, closing the stuff that would not have been approved in the first place isn't a huge amount of work, and not that much spam gets through and is easily dealt with.
