Interesting stuff, there is actually a wave of new mappers coming in which I am somewhat a part of. There is this blockchain crypto game called Upland which is a property trading game (for the most part). It uses OSM to tag properties with business markers (among other things). Since property tags drive asset values up, it’s in the interest of a player to tag their properties with business markers if the business exists, however, I’m sure many people will fabricate tags but we’ll see.
