Free websites that are aggregators of porn content. Some of the better known tubes are pornotube, xtube, pornhub, redtube, xhamster and spankwire. Some of the videos are pirated, and some are from genuine amateurs who get off from posting and having fans. Porn tubes have drastically changed the way porn sites operate. It used to be that porn viewers expected to take a short free tour and then have to subscribe with a monthly fee. Now, it’s possible for millions to see porn for free, with the price they pay is to see ads, links, an endless stream of pop-ups, and countless viruses placed on their computers or credit card numbers being pirated.
