No, but since moving out of the big city, therefore no Craigslist ads anywhere near closeby, I've been checking Facebook Marketplace for used record ads. I wasn't long before Elvinyl ads started popping up continuously. I imagine there's ample money behind that venture in order to create that link.
I have also moved to a much smaller town and the online classifieds here never have anything good around here if you want anything even something for $30 to $50 you have to drive 2 hrs one way not worth it. I have noticed over last 2 or 3 months Facebook has started to run ads from online business these ads will drive a lot of people back to Craigslist or Offerup.
I have done a little searching on this site looks like all the stuff is early 70s and older another thing I noticed the search does not work correctly. I searched for Mariah Carey and I only got stuff from the 60s and 70s looks like this site is only a month old and the search engine needs to be fixed.
It is possible the site is fake kinda like Wish.com
