Doesn't work. Doesn't block sites. You add them to the list and the pop-unders keep apperaring anyway, so you add to the Blocksite list again and get the message: This is already added to the list." Really? Then why do you keep allowing it to open up again if it's already added to the list? Plus, why are you forcing me to give it a rating star by making it a 'required field'? That's cheating. You are stealing reviews. This is a negative review not a positive one. I don;t want to add a star I want to remove the stars. Stop cheating on the reviews, guys.
BEWARE: In order to post a review they force you to give them a star, which is simply cheating and lying to people. Blocksite needs to fake its ratings.
