As this project appears to be fairly unknown in the fediverse still, I’d like to use this opportunity to advertise Flohmarkt. This Fediverse equivalent of Facebook Marketplace already has some instances up and running - see here: https://codeberg.org/flohmarkt/flohmarkt/wiki/flohmarkt-instances
At least when I used Craigslist, there was no social network element to it, so it was difficult to determine the trustworthiness of any given poster.
For that reason, I don’t want a Fediverse clone of Craigslist – I want an existing Fediverse platform to add a marketplace. I will not use anonymous marketplaces.
What if you could log in with your Mastodon (or other) Fediverse account, and they would too, so you could see their user history and connections? (And they could see yours)
If you feel any kind of meaningful trustworthiness from a Facebook profile, you’ve probably got some other things to worry about…
