You think Chase is active on DDF? That's awkward!
Chase (along with others) has hired people in the past to track down and shut down people trading and selling miles as well as other loopholes/glitches, DDF comes up in google on almost any subject. For the life of mine I cannot understand why people post their real names on the DD FB group and then they wonder why Chase shut them down.
Dan was invited to chase along with other miles bloggers to discuss the Chase cards, how do you think they found him? They saw he was bringing in tons of new applications and checked out his site and saw he was influential on this matter and wanted his along with others feedback on chase offers.. so yes, Chase knows about dan's Deals and the forums.
