Hello @Sarah-Shiner0
Yes there are many posts here on the forum concerning duplicate listings being removed. Your particular hosts have been flagged by AI as trying to circumvent previous bad reviews by creating a new listing. The fact that they have since addressed the issues doesn't seem to count unfortunately and it is very difficult to get re-listed.
Here is the policy in question and why the hosts are being banned from listing again:

There have been cases where a new owner has bought a place previously show cased on Airbnb with good reviews and being flagged as a duplicate but one with bad reviews ....
The advice usually given is to list on other platforms or create a direct website. Not great I know.
