Why assume that? Person W is welcome to have thousands of unique IDs if they want to, so long as when site X bans identity Y, that ban is applied to all of Person W’s present and future identities. Whether W has a single Y or a thousand Y makes no difference to me. I suppose some sites will care to restrict participation to a single Y per W, but e.g. in the general browsing a site with crawler/bot/AI shielding such as Anubis today, it’s completely irrelevant to them what your Y is so long as rate limits and bans apply to all Y of W rather than to the presented Y alone.
