Real answer: We probably won’t, just like every other website.

Some of the big places might have their own copies saved but most instances can’t afford to operate like that.

There are only a few variations in popular use, if it bothers you that much, filter them too.

If anything like this becomes widespread, you can bet people will figure out all sorts of ways around it and if it becomes problematic enough, they’ll probably just stop using it entirely.

Sure, there’s been talk of banning encryption as well, but practically speaking, that would be an unmitigated disaster in terms of security alone.

Technically possible? In the strictest sense, sure I guess?

Practically speaking though, it’d probably be a mess to manage and likely trivial to circumvent for anyone with a little knowledge and an IQ above room temperature.
