Please, please don't go into hosting believing that Airbnb will handle 'any controversy'. I hope that your journey as a host goes smoothly, you host lovely guests who leave you glowing reviews and that there are rarely any major hiccups.
However, in order to make that possible, YOU need to ensure that happens. Of course, every stay is a risk, but a successful host learns how to reduce that risk, e.g. by having a clear and accurate listing and clear house rules and ensuring the guests read all of it (again, don't just assume they will as most don't) and vetting guests to make sure they are a good fit, looking out for red flags etc.
Airbnb's verification system is far from prefect and, although I do want to see that guests are verified, it certainly doesn't weed out all the scammers and is pretty meaningless in terms of general behaviour. After all, the guest who throws a huge unauthorised party at a listing still has ID to buy the booze right? So, don't rely on that.
The fees you pay to Airbnb are for using their platform to advertise your listing. Guests pay much higher fees than hosts and are much more likely to stop using the platform if they are unhappy about something than hosts, which is why Airbnb tends to be more guest centric when it comes to both their policies and how they handle disputes, damage claims, unauthorised refunds and retaliatory reviews.
Why do hosts stay on Airbnb? Well, because it is the biggest marketplace for STR out there. Again, that's what we are paying our fees for - the exposure. For a UK homeshare host like me, there is no viable competitor - not even close. That doesn't mean that I think Airbnb is going to 'have my back' should something go wrong. They might help, they might not. To be honest, it totally depends on the customer services rep you get on the line. Some are great, some are terrible and don't even know Airbnb policies. It's hit and miss.
I really wish you luck on your hosting journey, but please go into it with your eyes open. It can be very rewarding (and I'm not just talking financially - it's certainly not a easy way to make money) but it can also be very challenging.
