@ELITE-Gymnastics0 I see. Well, I don't quite understand how your daughter was even able to contact the host on the Airbnb platform in the first place- as I said, 18 is the minimum age to open a Airbnb account, and without an account, you can't contact the host. Unless your daughter found the ad for the place somewhere not on the Airbnb site.
Many hosts do have their own private rental websites, in addition to listings on Airbnb and other rental platforms. But most legitimate hosts report their earnings, and pay taxes on such, no matter where they get their bookings.
I didn't know that Thailand was one of the countries where passport info for guests has to be collected. The host for sure sounds sketchy on all fronts.
I wasn't suggesting that you would let your daughter get away with this, it just sounded strange that she could organize and carry this out without you being aware. But having raised 3 myself, I know they can be clever- telling you they are spending the night at their friend's house or something else innocent-sounding. When mine were that age, I would phone the other parents to confirm. Once my daughter wanted to go to a party at that age and I phoned the parents of the kid who was having the party to make sure there was going to be a parent home. The mother assured me that she and her husband would both be there the whole time, and said she fully expected to get lots of calls like mine, but that I was the only parent who had checked.
And I see you are confused about the Airbnb platform- you wrote about all this on your Airbnb profile info, making threats to Airbnb. A profile write-up is for hosts or guests to introduce themselves, speak of their interests, etc. No one from Airbnb is going to respond to your profile write-up. You need to contact Airbnb customer service directly to file a complaint. You can do that by phone, message, or on their Twitter account.
They won't do anything about the passport or under-age party issue, because the booking wasn't made through them, so don't even bother pursuing that angle, but if your daughter communicated with the host originally through the platform and there is a message you can access where the host asked your daughter to contact her privately to book, they won't like that because their booking fees were circumvented and may suspend the host's listing.
I would also presume your daughter lied about her age and intentions to this host, as no host, no matter whether they are trying to avoid paying taxes, would want a drug and alcohol-fueled party of 12-15 year olds at their home. So while the host did not act honorably, I would be pretty sure they were lied to from the beginning.
