Yes, i also do have those kinds of friends.
Dude, take it in positive ways. The world is full of colors and those friends are one of those colors. Please do not hate them because they are what they are.
As other friend says if you don't want to see their status or any activity, just unsubscribe them. That is what i do. Make friend to everyone no matter how irritating they are. You never know when they might be helpful at some point of your life.
