I would host independently minded guests that don’t want/need hand-holding, and guests that are vetted for being socially respectful (tidy, no 3AM drunks, etcetera). My property is tobacco and alcohol free, which surprises friends, so I can imagine strangers being disrespectful.
Do trustroots.org or movingworlds.org provide filtering? I really never want to have to trawl through reviews, because I find it wasteful and also I think reveiwers tend to avoid writing anything truthfully negative (allusions and omissions might occur, but are not always obvious).
