Once a newbie creates a new topic, the moderation team must approve it first. I wouldn't suggest posts generally because there may be some honest newbies that face an issue. Just for their topics.
No offense, but assuming this is your only (or oldest) account, you've only been on bitcointalk since roughly the time COVID-19 started becoming a real problem. And the reason I bring that up? Because it's obvious to me that you haven't done enough reading--because if you had, especially in Meta, you'd know that suggestions like yours have been brought up before and they invariably get ignored by Theymos.
Scams aren't even moderated on the forum, so there's no way Theymos is going to put the burden of judging the legitimacy of a newbie's thread onto the moderators. And I'm not even saying it's a bad idea, just one that you can pretty much forget about.
My suggestion to you is to read more and figure out what the culture is like on the forum, how things work, what the "leadership" is like here, and so forth before you start making recommendations on how to improve bitcointalk.
