There have been some real scams, and some mis-use of the AirBNB bridge into rental space occupation. The very first request I received in 2017 came a day or 2 after a troubling gov't announcement. The request, itself, was troubling; culturally dystonic photo, language that - albeit not foul - just did not fit with the person purportedly expressing herself, among other things that were 'just not quite right.' Some ID info seemed to be lacking; this allowed me to reflect for 24 hours, confirm the dates and politely ask for ID completion. It is my believe that my host response never reached the requestor; no response came back to me. I felt relieved! But I lost my 100% response rate!!
Another 'not-quite-a-scam' is the full-season high-rate 'guest' who in turn, subleases. No thank you!
