@Helen3 nope, I don't believe it. ABB ~may~ run a background check, may not & there are certainly plenty of stories of bad actors being in the system.
ABB specifically state they will NOT share any ID info with hosts and guests are allowed to change their name & photo at any time to anything they like. Anyone could appear, cause a problem and then disappear and ABB will quite likely do nothing. I'm not willing to take the chance.
ABB makes an introduction, after that I take responsibility for knowing who is in my home.
I have a contract not to create a tenancy, but to be clear that there are no tenant rights, that they are responsible for themselves and the space while they are here. We provide no liability coverage for them, their guests or their belongings and they sign off on knowing that they, not ABB, are liable for their actions while they are with us.
Agreed, my way is certainly more detailed than most hosts, but it's in the listing and it's my house. I'm not interested in hosting any guest that isn't willing and able to tell me who they are and that they understand that they are responsible for taking care of the space. Given that my ABB reservations have absolutely no security deposit in hand it seems to be the only protection available.
Of course, if that level of detail makes a possible guest stay elsewhere then that is ok with me.
