Mine is from a few new, recent conversations (phone, in-person) about renting my condo on Airbnb, specifically about 3rd party management services. I just started getting targeted for manorshare, one of these services. This company was never vocalized or typed. I don’t have the Facebook app installed.
My only explanation is that I searched for several far future dates for pricing on airbnb in my condo complex. airbnb knows my email, knows I searched my own home thus indicating I’m a potential lister. Airbnb sells/leases this information to manorshare who then used my email on Facebook for direct targeting.
