So, I ended up just saying "screw it" and removed them. There are a gazillion online shops that accept BTC, and they aren't on coinmap. Coinmap, and openstreetmaps, are maps, not meant for online spamming.
Good job, I'd say. No one is served by empty locations.
My next question is, is there a way to see all of the new businesses that are added to coinmap? It's really cool checking from time to time and seeing 20 new locations on coinmap, but I never know where they are. I'd like to see all of the new ones every day. Is this possible?
It would be cool indeed, but it doesn't add any direct use value, so I guess that is why it hasn't been implemented? I would like to hear a reply on this too.
