@Jan9567 For sure, it's logical that one bad review among 10 would lower your rating, but it's not necessarily true that hosts with lots of reviews are at an advantage in this respect. They get more guests, so there is more potential for both good and bad reviews. If they get 10 low ratings out of 100 guests, that's the same percentage as your 1 out of 10.
The thing is, you started hosting at a time when hosts are experiencing the worst guests they have had in years. Peruse a few pages if threads here and you'll see what I mean. At the same time, Airbnb's host support has become a dismal affair.
It seems the pandemic has bred a contingent of new guests who are entitled and demanding and breaking rules. Whereas a couple years ago, hosts might get 1 bad guest in 75, now they are getting far more, and having to decline lots of inappropriate booking requests.
Superhost is just part of Airbnb's behavior modification tactics. Don't get hung up about it. Hosts who have been Superhosts, lost that status, regained it later, lost it again, say it didn't make any difference to their bookings.
Keep in mind your main reasons for deciding to host. I'll bet it wasn't to get 5* reviews to bolster your self esteem. For most of us it was to earn either some extra income, or to be a major source of income, because we are suited to that sort of occupation, to get good guests who will appreciate what we provide. It's about getting bookings and providing good hospitality. Reviews and ratings are just an unavoidable side effect of this business, like having to wash blood stains out of sheets and pull guests' hair out of the shower drains, not that important in the grand scheme of things.
