I do not follow this logic... that is not to say I am correct and that you are wrong. I am always happy to discuss and learn and change my opinion.
They can still ask these questions on the junior boards. Those even attempting to join in and contribute to legitimate and worthy discussions can be given merit. I would find going there browsing through a selection of good threads, then meriting those making real effort to help or even joining in conversations of worth and interest far more rewarding than reporting 100 spammers, ico bots, post pasting bots and then the mods have to confirm and delete and take action. This is a wasteful and unpleasant process and it is also a very centralised bottlenecked process at the mod level if doing it this way. It is also a very negative thing to report person compared to giving praise and merit.
You are not to expect highly detailed knowledge of conceptual design and coding from anyone on this board including legends of course only a willing and helpful attitude to contribute and converse with others.
I am not really complaining at the obvious tech brain drain and dilution since the days of hardcore bitcoiners - that was always going to happen. Let's be honest what percentage of the board actually would have the capacity to understand many of these designs at a deep math level. I don't think it's essential most need to understand at more than a very basic level. However the board is now nothing to do with the tech or about the aim of creating decentralised trustless networks... it is simply becoming a marketing board for icos through various posting techniques that make the board almost worthless to anyone other that to hammer the search function for specific details you may want to look up from years ago.
Having a sensible vetting period that is semi automated is the obvious choice. This will be a decentralised vetting process since those with the most merit to give will be free to peruse the junior boards and all be mods in a way.
You're sort of asking the newbie jail to be bought back. Stopping people to post in the main boards is not a good idea. Although you can still merit users in any board you want to. That is much better because more the boards, more the posts to merit.

I believe no one has so far liked this idea, it would be better for a better suggestion, a user friendly one, or you could just merit users, report a few and have good discussions, eh?
Well let's be honest reading the replies from most it seems they are not getting what the idea exactly is. It seems they think they are getting all posting rights revoked.
I think a vote from senior members and above might be quite a useful poll.
Please validate why stopping people or bots having immediate posting rights on the main board without first demonstrating they are willing to be useful willing participants in the spirit of the board is a bad thing...
Even though they will have immediate posting rights on a junior board where if they do prove to everyone with smerits to give that they are useful or even just willing to abide by the board rules ...then they will in a decentralised way be approved for starting topics on the main boards.
There has been no better alternative offered and leaving it as it is now is just turning the board into 90% garbage actually more likely 95%
They removed noob jail because it was not possible with the volume.... this is simply a noob jail that is able to cope with huge volume due to more or less decentralising the mod process.
Like we said they dont need to give anonymint level posts or answers just show they are genuinely interested and helpful.
