Do you expect that a year from now (or two, or however long you think is a fair amount of time to pass), online reviews will be noticeably better/more useful than they are today? I think the underlying thread here is that most people don't expect this to be any more effective than anti-spam or anti-robocalling calling rules.
And by the by, I get significantly less spam and phone calls than I used to. Vastly fewer and they're all clearly scams now, which makes it easy to ignore.
