Hi Fiona - If your is not set where someone may instantly book your place without your permission (there are some guidelines), your listings are automatically filtered out. If you have noticed a drop in your bookings in 2017, this is why. There was no warning. Today I have just found out that I cannot require an ID of my guests unless IB is turned on. This is absurd. I have written to Airbnb now - this may help you understand the downsides to IB, and the issue I take with it in general:
A year ago, without any notification to hosts whatsoever, Airbnb automatically filtered out listings who did not have Instant Book turned on. After a month of having little no bookings and wondering how we were going to pay our bills, we stumbled upon this fact and only then learned that we had essentially been hidden from all users without any warning. Your company has forced our hand into turning on Instant Book just so we can continue to use this platform, causing major inconveniences (such as limiting our ability to choose when to accept one-night stay is available to fill a gap, or when it is booked three months in advance in the middle of an entire week).
Now today, I go to turn off Instant Book so that it a booking does not occur during a time when we are out of town (and no, your reservation requirements for specific dates do not work in the slightest), I see that your company is no longer allowing us to protect ourselves securely in our homes since we have turned it off. Apparently security is only offered to a select few.
Just to give you a bit of a backstory here: before our hand was forced into Instant Book in 2017 to make even $1 on this site, we were ALWAYS permitted to require an ID for guests to book with us. This was a no-brainer. Now, Airbnb has decided that security is only for the folks who fall into the ploy of Instant Book (or, for those of those who can actually manage to do it), and has removed the right to requiring a government-ID. This is shocking, and disgusting.
For such a PR ravaged company, with countless stories of thefts, unknowing sex parties in private homes, major damages and incidents, and physical and sexual assaults (and even a false imprisonment case!) that have made the news, this comes at a huge shock. I'm not entirely shocked that such a big company like Airbnb doesn't care about a host's safety anymore; I'm entirely surprised that you don't care more about your image.
I have been a fiercely loyal Airbnb user and host for 7 years. In fact, we have just received Superhost status today for the fifth time in a row, and this news of removal of security was the congratulations I received. I was on the fence last year, but it's clear the time has come for us to seek out Vrbo, Tripz, Homeaway, Flipkey, and Wimdu when welcoming strangers into MY HOME. I will now book personal trips through others venues at every opportunity I can get, as they do what is right by protect their hosts' security. I will encourage others and my media contacts to do the same until this horrible policy is reversed.
Regards.
