I am one of the frequent Facebook user and I have set autopost my blog posts to Facebook to ensure the process is done automatically without adding each link post manually at Facebook. There are some friends who give comments on the notes which are imported from my blog posts. I get a friend’s comment which looks like a suspicious comment that want share a link to me. I wonder whether this friend’s account has been hacked or the Facebook notes application has a loophole.
I don’t know how they can access the notes page and leave a comment using my friend’s account name but Facebook Developer fixed this problem in a lighting speed. Excellent. The comment was deleted automatically when I view my notes again. Maybe a lot of people have this same issue with me and reported to Facebook earlier. Now, you need to enter Captcha value when you want to comment on a notes. I try to reply to the comment and even I am the owner, I have to enter the Captcha! I can say that this is still buggy and hope Facebook team fix it as soon as possible 
This issue will not happen when I am commenting in my own profile page.
