This is pretty much what I already suggested in the community generated suggestions thread:
https://bitcointalk.org/index.php?topic=4893744.msg44062249#msg44062249Requiring manually whitelisting of all new accounts before they can post. All new users will essentially be shadowbanned until they've been verified by a mod. This will eliminate 99% of bots and spammers before they even start. Spam threads can be trashed on sight before they even become spam megathreads.
And beside what are the criteria of a good post. What might be trash to you might be treasure to another so one person can't decide what's should be allowed to be posted.
Moderators already get to decide what is trash or not so this isn't really any different.
This kind of safeguard to spam will ironically lead to spam attacks.
How easy it would be to flood the forum "pending post" database with huge numbers of posts to delay the moderators - Bitcointalk would have no chance.
As easy as it is to spam it currently. I don't think there's any logic to what you're postulating because if this was going to happen then they'd be doing it now where it will have more exposure. Staff already have to handle and deal with spam so the only difference is whether it be public or not. At least everyone else doesn't have to see it and spam threads or bots will never make it through the net making the forum cleaner in the process.
So I postulate that any time a user makes a new post and submits his/her post, this post is made unavailable to other users,but to the MODs in charge of that very section,who's gonna scrutinize the post
This will never happen:
Limiting newbie participation is very harmful for a community. Newbie jail will never return: I consider the newbie-jail period to have been extremely damaging to the forum. When barriers to participation are too high, then the best people often just won't go to the trouble of joining, and the people who are willing to jump through the hoops are often people who aren't good for the community: people with nothing better to do, scammers, get-rick-quickers, etc. Having a permanent newbie jail policy would improve things a lot in the short-term, but would end up being a fatal poison to the community.
This isn't really what's being suggested though. Theymos even put the suggestion in the 'maybe' category so it's not out of the question:
