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: (I was slightly wrong: keep reading
lower)
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.
if it's meaningful and not redundant would make it available for all to see.
There's some irony in the fact that what you're suggesting has been suggested before. Your post would have been rejected by your own suggestion, creating more work for the Mods.
