Facebook blocking system overloaded?

[Elmer]

There are multiple pages online of guys posting pictures captioned "Like if you agree" and in the comments "Subscribe for 1000+ friend requests" and other such things. My friends are stupid enough to like their pictures and they keep showing up on my news feed. When I try to block them, I get a message saying the Facebook blocking system is overloaded, but I am able to block normal Facebook users. Why is this happening?

Facebook's full of viruses and it takes them a lot of time to get rid of the hard ones, still saying that they open doors for developers and freedom but don't consider security.
What you can do is, either contact a site admin so hit "Help" at the bottom and ask them this same question...? Or you can just select your news feed friends, so it only shows posts from the people you want
