Bonus point systems or just ignoring ratio solved this from my pov for trackers, the 1 to 1 ratio stood out as something that would need a solution long term.
I'm wondering, is there some sort of California-specific tax/zoning loophole that allows this but doesn't allow nightly rentals ala Vanly or Boondockers? It's the only way that this makes sense to me.

Plus, at a measly 20 families right now, all in DC, it's unclear whether this model would work for bigger or more heterogenous groups. Probably at a smaller scale, the expectation of reciprocity alone would be enough; at larger scales, "financiers" would probably try to game the system and skew exchange rates. In my (limited) experience, this sort of thing only works when a group is both small enough and homogenous enough that the primary driver is community and mutual respect, not any real sort of economic game theory. At that scale members don't tend to hyper-optimize for individual "wealth" over collective gain (yet).
On a certain movie tracker some invite selling scum would join via the signup process that used to exist on reddit, cheat a bunch of upload on popular torrents, convert that upload into bonus points, launder the points to their main account through a forum contest where they also gave away BP to innocent users, and buy invites to sell for real $ with the laundered BP. Similarly the dummy camping accounts could make sure to mix in some legit hosts as their free stays by picking hosts that may not be around/able to verify the dummy account stayed at their location (because it didn't).
