Running a GSA SER "honeypot"

Has anyone out there ever experimented with purposefully setting up a basic web site, but with multi-user content posting enabled (Wordpress/Buddypress/Drupal, etc.)? The idea being that yes, you'll get nothing but unrelated useless spam from submission tools posted there. But over time, you'll also get a ton of backlinks.

I ran across one website in the agricultural space that had thousands of indexed pages and well over 1.5M backlinks pointing to the domain. It's DR from AHREFS was above 30.

What I'm wondering is if anyone has ever tried running a domain, attracting lots of content posting and backlinks for a long period of time (I suppose 2-3 years or more?) and then wiping out the submitted content to "clean up". Most likely with internal 301 redirects, either just to the home page or over to original, high-quality posts of your own.

Has anyone actually tried something like this? What were the results?

I used to run a load of these, a couple in each of the main contextual platforms, still have a few running. But it wasn't really for getting backlinks that I was running them, I was more interested in looking at niches.

Why you should actually waste 2-3 years of waiting and get links with a ton of irrelevant anchors with a shit ton of different niches articles,
While you can build links with more niche relevant content, anchors, etc...

Surely your plan can work, you can even accept free "posts" in the website, add some GSA footprints to the content, or whatever similar tactic,
But it will simply make it way more spammy with less chance to actually work,

It can surely work for some, but much others will simply get vanished from the SERPs,
Even building your own GSA links using a good list, content and indexing services seems to not be working as well today

Like the thinking, but Google will mark the site a spam long before you get chance to use the power of any links gained. Even a 301 wouldn't clean the history.
