Is there any #Fediverse or #ActivityPub development underway for classified advertising?

I've proposed reviving #WantAds as a revenue source for #LocalNewsMedia, particularly as online commerce becomes difficult for small business and riskier for customers. See the white paper on TechNewsLit.com: https://technewslit.com/explores/explores20240511.html

The Fediverse seems a good fit for #ClassifiedAds as an open-source backbone and ability to federate into regional networks.

Ideas welcome.
