@Laura427 The same person contacted me with an enquiry with the same wording (his name is in your tags). A bit creepy, wasn't it? I said I couldn't but offered to answer any questions. I flagged his message, told Airbnb why, heard nothing from him and later declined. An enquiry won't block the dates.
I should have flagged his profile, but forgot, and now his enquiry has disappeared and I do not have a link to it.
He also has no verifications, and booked a twin room for only one person instead of my (otherwise identical) single room and it was for 5 nights - so he had made it quite an attractive potential booking, trying to tempt hosts.
Interestingly, his email address passed Airbnb's screening because he had put spaces between parts of it. (I'll have to find a way to report this).
Anyone else?
