Should TLC cancel Extreme Couponing for glorifying coupon fraud?

Since this show aired, many stores have had to change their coupon policies because of coupon fraud and shelf-clearing techniques used by shoppers. This makes it harder for the everyday shopper to use their coupons effectively. At least one "Extreme Couponer" is being investigated for fraudulent use of coupons. Shouldn't TLC be responsible and share this information with their viewers? The show has put unreal expectations in the minds of their viewers who mistakenly believe that they can get the same results.
