I can tell you this - arguing about minor detail like: is it alright to sell these keys because they are violating civil or privacy laws or breaking TOS
is not gonna lead you anywhere. We all know it is somewhat grey area. So either Vod  and every 'scambuster' here will become vigilant enough to mark EVERY MSDN seller and others who sell: HBO, NETFLIX, various service subscriptions, various other account sellers, premium services sellers and WHOLE other LOT of people who are dealing with this stuff right away or just stop and leave it be.
