When porn meets fashion and fashion meets porn

Last week Diesel announced that they are going to start advertising on Pornhub (the largest online pornography site with 2.1 million views per hour). More people visit Pornhub each month than Amazon, Netflix and Twitter combined.
We're so desensitised from this already (from the likes of provocative music videos) that porn isn't becoming anything other than the norm; so doesn't it make sense for Diesel to advertise their clothing brand there?
It's already common knowledge that Diesel are notorious for not playing by the rules, yet are ardent fans of maintaining relevant and contemporary - hence their latest campaign (now featured on Pornhub), which decodes the idea of digital culture; from emoji language to hashtags.

Moreover, most recently announced is that porn actor Colby Keller is the new face of Vivienne Westwood SS16. The campaign sees Keller go full frontal around various areas of Venice, (shot by Juergen Teller) in alleys and canals as to highlight the recent damage done to the city over the past few years. As with most of Westwoods campaigns, as an avid environmentalist and keen campaigner against fracking, the shots portray an environmental awareness - a city with a landscape once so beautiful that is slowly decaying.
