I have seen his writings and reviewed the Facebook group.

Most areas have zillow and facebook groups where everybody goes to in the area to find whats available to rent. 

I think a better analogy isImagine I am selling my widget by advertising only on Facebook.

Facebook Groups in your area also help but need to vet a  lot!!

I guess the main reason they would want a site is for something that will consolidate all their properties under 1 brand name that they can post on face book and other sites or give to friends and family.

Has s/he marketed it on social media, reached out to their network, ran Facebook ads, held an open house. #4 Are you offering a BAC?

Facebook marketplace may be a bit more work butdefinitely worth exploring and looking up reviews for different brands peopleare selling.

I can't say I've ever heard one single solitary story about any of these potential scenarios actually happening despite a relatively high number of STRs leaving wine etc as a welcome gift.You'd think by now we'd have at least ONE post in here or in the hundreds of STR facebook groups about someone that left wine as a welcome gift and got sued after a drunk person had an accident, or got reamed out by a recovering alcoholic, etc. 

DM me for links to some Facebook groups that tenants and landlords use to find or advertise properties.

Also you could joins some STR groups on Facebook.
