Are we talking about the console or ordinary user terminals.

I remember some systems, maybe TOPS-10, VMS, and Unix, that allow one to
write to any terminal. Maybe also supply a special command for doing it.
I haven't actually thought about it recently, though.

But I think also have the ability to block them, at least ones from
ordinary users.
