Can people see whenever I like/reply to someone else's *comment* on public post in Facebook's ticker?

Okay, what if I'm liking a reply to a comment (again, on a public post)?

[abraXus]

yes, they sure can, even if the post isnt public

they just can only comment themselves when it's public

but only people over 18 have the public option

but they can still see it if they are under 18 too

the rules are different for people under 18 and people over 18, and people who lie about their age get their account suspended

Yes

[Dora]

Yes, they can see it.
