Spectrum puts account and security code on every bill page, even ads

My Spectrum bill had 3 pages this month: 2 pages of advertising and 1 billing page. I was about to throw away the 2 ad pages but noticed that the ad pages have my personal info, including full account number and a 4-digit security code at the top of the page. So I have to cut those off and shred them. It's no wonder there are so many security issues these days.
