Facebook.. is it possible for someone to block your messages, so that they wont be delivered to them?

[568]

I sent a message months ago to someone, and I know that this person has logged in to FB, and had to have seen my message.. but when I checked in messages, its show as if it has not been read at all..

Is it possible for someone to block only your private messages, so that they wont be delivered to them?

or do you think my message was read, and was just marked after as "unread"?.. and maybe that's why it show like they have not read it?..

I would like to know your opinion..

Thanks.
I not referring to if I am blocked, because I know that I'm not..

What I'm asking is, if someone can block ONLY your private messages?

yes he can block you, and one more thing can ensure that is, you can see "seen" time in your chat box. It will tell you that he/she has seen your msg or not.

Yes, he can block you. Your anything wont be seen to him. You can go in messages and see if "Seen at *Time* is written there

Only if They Block you Completely That Would Be the Only Way Other Than That No
