Boo American Express. Boo, hiss, shame on you! UnderCurrent is not impressed with Amex right now. Despite Proper Journalist giving your spokesperson a full article to reply to Visa's attack, you've resorted to the lowest form of internet manipulation: Astroturfing.
Earlier today, 'Frank' posted a very pro-American Express comment underneath the original Visa campaign article. In this comment, Frank describes himself as an "Amex merchant" and explains why he prefers Amex to other credit cards. He also describes Visa's campaign as "childish" and "bully tactics".
UnderCurrent thought this comment was too good to be true, so it looked up Frank's IP Address and, holey moley, it's registered to American Express.
