I get what you mean completely, but as I mentioned in my suggestion from two years ago, submissions would still go live, just like they've been since day one. By a "queue" I meant a mod or admin will simply make sure to review that entry has sufficient info and is game-related, not just a literal blank entry or one for a Toy Story or TMNT toy that has absolutely nothing to do with video games (unless it of course is one related to a particular video game); and by "sufficient info" I mean an entry has at least the required info fields filled, like developer/publisher, release date, genre, barcode, item number, just to name a few examples, where in the event said fields aren't filled, then the mod or admin that's looking over the submission could, at the very least, fill some of the fields. I personally disfavor users who submit a new entry with no information whatsoever; I used to go through some of these entries filling all the required fields, but I simply got tired after the umpteenth time and gave up. To complete my point, any good submission upon review will remain live, but bad submissions will obviously get rejected and deleted. This, I honestly think, could help reduce double entries, as well as it could mitigate users that have a tendency of submitting unrelated entries, dupes, and/or bad/erroneous info. Personally I think blacklisting these type of users would also help. I reckon, as you said, we have the ability to report bad and duplicate entries, but I feel, even though this is a user-driven website, as most of these type of websites tend to be, it shouldn't necessarily be the user the one that "does the work", if you know what I mean. I'm not saying that this system will supplant us as users reporting dupes or bad entries, it should still be there, because at the end of the day dupes and/or bad entries will inevitably creep their way in, but having a system set up that alleviates this from the get go I feel would be beneficial to the website. I'm not implying that by implementing a system like this we'll have a structurally sound website, but, again, helps appease disorder.
VGMdb has a system akin to this, and it works. Entries for soundtracks go live as soon as they get submitted, but get reviewed for approval and either accepted or denied, with the possibility of the user getting a message to provide more information if possible in the event none or little info was provided. And even with that system set in place, they still encourage their users to report any bad/erroneous info or duplicate entries, just the same as we do here. They have nearly the same amount of mods and admins that we have here, but they're devoted to their website, I feel. I certainly mean no disrespect by saying that to the mods and admins of this website, I don't want to sound like an ingrate, even though I probably do so to some, but that's been my impression since joining here.
