@Adam-and-Carol0, I can understand forbidding a local to book, but how would you want to forbid them to see you? Everyone looks at the competition now and then, if you are aware of cookies etc, you do it on a clean browser, not logged in.
if the programmer bases this on location, you would lose all travellers already in your town and needing a room for tonight or for an extension of their stay after their current rental.
for the damage claim: yeah, good advice, but it does not always work. I tried whatever I could, calls, new claim, the same supervisor grabbed different claims and denied all of them with absurd justifications. Even if the opposite of her statements was easily verifyable in the data base or reading a few reviews. Seems they can put a flag on you or the guest and pull all files to them. No idea why.
