If you send someone a message on Facebook and block them before they read it, do they still see it?

[boo]

If so, can they reply?

[Angeleyes]

Once you send a message the person will receive it regardless whether you blocked them straight away, the only thing is they cannot reply to you as you have them blocked.

[abraXus]

yes, they will still be able to see it

not even deleting your own account can prevent them from seeing it - it's like email in that way

[Divas]

Yes they can read it bt your name won't appear. The receiver cannot reply you after you block them.

[tylertremallose]

yes they can read it, just not reply.
i dont think it even shows your picture
