Blocking someone on Facebook?

[Andrea]

There were some people on Facebook arguing with me over something stupid and just would not let it go to the point they were spamming my friend's post. So I blocked them so I didn't have to bother with them anymore.

I can't see anything they post now. If I continue to participate on my friend's post, can they see what I say after that? or will we be invisible to each other?

You will be invisible to each other but they will be able to see responses from other participants.

[Lauren]

Yeah you'll be invisible to them and vice versa.

[Elaine]

Invisible to each other.

they cant see your posts like you cant see what they post, also any messages between you guy from before you blocked them will say facebook user without a picture too
