Mate i am Muslim just to let you know, i don't watch porn let alone download it. So your sense of humour is wrong in here, although i like humour very much.
I doubt it was a joke and was sound advice to prevent infections. When Ever I help someone clean their computer from a virus I tell the not to watch porn online or if they must have to to go to redtube, Pornhub, Xhamster, yourporn, ect... and don't click on any ads even if they are an older married couple and always hear the same thing that no one watches porn.... but they always are getting infections that usually come from going to shady porn sites ... why is that?
I would lime to say a website called thumbzilla is great, owned by ph and no ads. Keeps the computer safe and lets be real most people need some alone time. The stupid ones click on ads and unknown sites.
