Looks actually quite clever from my end....
You get a site selling domains, which YOU (only you, lol) consider to be valuable, and you list it for a massive price.
Now it appears in all the Flippa ordered-by-price searches in first place, which gets you eyeballs. Eyeballs on your SITE, and on your domain portfolio.
A good few suckers will then try to purchase domains from you, as they fall for the hype that the domains are valuable (they MUST be, if 400 of them are worth 27 MILLION!!!!).
Your "benefit" is on all the sales you make of domains on your crappy site (you didn't have to have valuable domains, you didn't need to SEO to get the traffic, etc, etc)
Your cost = ONE Flippa listing fee...after all, it's not ever going to sell, so you just keep getting free re=listings for it...you keep ahold of that top spot for as long as you like (or until someone lays out your method as I'm doing and then places their own listing for 200 Million, lol).
If, like it looks like happened, a buyer accidentally hits the BIN button = no problem, he's not going to go through with it, so you report to Flippa and they just give you...yep, you guessed it...ANOTHER free re-list!
Lol...imho this is "thinking outside the box"...and the guy can't even write or spell properly, hahaha
