But none of what you mention is a valid for assessing the quality of information coming from a given user.
This is why a separate and new grading system would be required.
And the beauty of it is that you can choose to use the vetting or not.
I see your point, and it has some merit. I'm just going to say that my understanding (and Mods please correct me if I'm wrong) is that being a moderator here at R2R is a tough, and largely thankless, job. I just don't see logistically how they would be able to vet everyone. I mean, would there be a questionnaire? Could such a questionnaire not be spoofed by, I don't know, Chat GPT? Would a staff member of R2R have to go visit each person and observe their tank? Is having a tank even a requirement for participating here? Again, good idea, I just don't see how they'd do it :-)
Someone earlier mentioned a "downvote button". Also not a bad idea, but I know that people will get downvoted just for having a difference of opinion, not necessarily a bad idea or post. And that I think leads to people not wanting to share ideas and different points of view.
Badges, I believe, are a good indication of someone's background and knowledge. Certainly, all of my badges I got by either purchasing a supporting membership, welcoming new members, carving a pumpkin, and playing Santa Clause. Clearly, no one should take me for any more than an active R2R user, not an authority on anything. But when I see users post with badges like "Expert Contributor", "Moderator", "Excellence Award", "Article Contributor", "Fish Medic", etc., I pay very close attention. So I think some of the vetting you're asking for is already baked into the R2R cake, so to speak.
