@Debra300 thanks for tagging me here.
@Haley182 I don't actually ask for guests' IDs. I do require guest to verify their ID with Airbnb (but this is not failsafe as I don't really trust that system) and to upload a profile pic. What I do is to state in my house rules that guests may be required to present official government ID on arrival. I don't actually ask them to do this, but sometimes they volunteer, seeing as I've mentioned it. The reason I state that is as a deterrent for people who think they can pull a fast one! It's worked so far.
BUT, I think the reason it has worked so far is that I put a lot of effort into vetting my guests in other ways, and a lot of this is to do with communication. I have rather a lot of communication with my guests prior to accepting a booking, but I do feel that is necessary when you are renting rooms in your own home and even more so if it's long term stays and even more so if you are a single female!!
I do know that some hosts request to be sent ID when the guest books. I don't do this personally, but I have had guests send me it without being asked, so I don't think it's that uncommon.
