How do I report a message or block someone on Airbnb?

To report a message from someone or block any future communication from them:

Go to Messages on airbnb.com and click the conversation with the person you want to block
Click Report under their profile photo
Select the reason you’re reporting this person, then if you also want to block future messages from them, click Next > Yes, block now

If you block someone, they won’t be able to send you messages, send you a reservation request, or accept a reservation request from you.
