Disabling Comments

About 80% of the comments submitted to me were just sugar-coated spam.I used to review and reject them, but I can’t take this anymore. :(I get all these seemingly wonderful posts... Comment: “You are soooooo amazing!!! I was going to go bulimic, but your site gives me hope!”But then it links to: “SUPER-DUPER WEIGHT LOSS PILLS! BUY NOW!”ARGH!!!!!!! I am so disgusted!!I find it despicable
