I can't message people on Facebook?

It says "Send message to blocked user
Message cannot be sent based on either the receivers' privacy settings or yours." I know it's not the other persons privacy settings so I don't know what's wrong cause mines on basic filtering

I think its about time you get the hint, maybe that person doesn't want to chat with you. Jeez stop obsessing already!

Just leave the person alone.
