This is going to be a pretty blow-below-the-belt suggestion for our (Polish) sensibilities, but since I have very little charity for antisocial behavior - especially of the "I profit, I don't care" kind, and doubly so when coordinated by a multinational corp pretending to be a hip tech company: I wonder if the owner is paying correct taxes on the money made from AirBnB leases. It would be a shame if the Revenue Service came and checked.

Considering that airbnb payments come through wire transfer (or SEPA), you'd have to be pretty dumb to evade taxes.

Yes and no. Are regular AirBnB hosts actually forming businesses, or are they reporting this as private income and hope the tax man doesn't have time to notice?
