I noticed an uptick in spam over the past four days. Curiously, all of it
On occasion, we may provide customer mailing list and email addresses to reputable, carefully-screened Mileage Plus partners or companies whose services or products may be of interest to you. (You may unsubscribe by Opting-Out.) Sharing of customer lists may also provide you with the opportunity to earn bonus miles for non-flight activity. We require strict contractual obligations from these third parties to ensure safeguards for the privacy and security of the information.
Opting out obviously isn’t enough. Then there is the matter of the carefully-screened Mileage Plus partners who
include the sorts of people who sell "Viagra",
"Propecia", "Vicodin" and something named "Cialis". These strict contractual obligations that United Airlines requires of it’s partners also allows for marketing even more dubious products like "Mini Keychain breathalyzer", "Digital Cable Descrambler" and "Diploma in 1 Week".
It’s clear that United Airlines associates with a nice bunch of liars, cheats and thieves.
