Bin, I'm sorry to let you know like this but I'm one of your so-called "friend"s.

The truth is that we are perfectly able to post on your wall, but we choose not to because we just don't like you.

We are not jerks so it is very difficult to tell you this to your face, so we just told you that something is wrong with facebook to try to avoid the issue.

Since you didn't get the point, we decided that we should tell you before you waste any more time trying to figure it out.
