You rented out your apartment to a stranger on the internet based upon what other strangers on the internet said about them. You almost certainly broke the terms of the lease in the process and probably deserved to be kicked out even if you hadn't had an "XXX freak fest" thrown.
Sure, AirBnB should try and figure out the damages, charge the accounts credit card(guarantee that won't work) and the pursue damages(good luck).
This is why people have renter's insurance(doubt you thought of it as you were probably trying to do this illegally anyway).
This is also why this industry is regulated, because when it's not humans get pwnt by their own stupidity combined with the malice of other humans.
At the end of the day for a lot of people AirBnB is a way to make easy money under the table, that's why there's little to no regulation; yeah that regulation comes with taxes/overhead, but it also comes with protection from the hazards of the business. It's pretty fucked logic to take such a huge risk with your property, give it zero protection, and then be not only surprised, but furious(with the site connecting you to the offender not the offender themself), when shit goes down. How dense can you be.
TL;DR- AirBnB pays for these situations anyway[0], this drama post is made by someone who took a huge risk in renting an apt without insurance, without a face-to-face, and probably not in accordance with his/her lease. The post will probably result in a faster payout, but the entitlement is slightly annoying considering the circumstances.
