Hotels do have a shared blacklist system. Why wouldn't they?

I imagine being a repeat complainer is one way to make the list unless you bring enough business to be worth it.

Hotels do not have a shared blacklist. And generally they don't care how much you complain as long as you aren't damaging their facilities since they don't have to try to make you happy unless they want to retain your business.

Chain hotels do have shared blacklists, yes (as far as the law allows them to, GDPR says hello), but unlike Airbnb in every major city there are independent competitors.

I have stayed in chain hotels in the UK, complained sometimes and gotten a full refund. Been welcomed back again with no problems.
