You put it on the public internet, the public has the right to see it, take whatever lessons it can and do what it wants. It's the intrinsic nature of the internet.

It has never been ok to say, "[this kind of person] is not allowed to look at my page nor, "you can only look at my page with [this web browser or other tool]".

What? Sure it has. “This page best viewed in Internet Explorer.” “JavaScript required.” “Members only.” “Aggressive scrapers blocked.” “Random country blocked just for having higher proportion undesirable traffic.”

All bog standard for decades.
