Ehh, mastercard and visa have been playing these kind of games for years. For example hypnosis is a censored term on most porn sites, and most try to take down videos using or referencing marijuana in videos. Not because either of those things are against the law to have in a video, but because payment processors like Visa and Mastercard will blacklist sites that don't of their own volition. Go ahead and go type hypnosis in any major porn site and you will see you get zero results.
