The sign above is on the back road in Patong (Nanai Road). The name "Porn" is quite common in Thailand, either as a nickname or as part of the full name. For example Pornchai, Waraporn, Siriporn, Somporn, Porntip, Thitiporn, Weeraporn or Supaporn - there are many more... but I cannot believe there is actually someone called "Pornstar".. surely not.
Even as a long time resident, quite used to seeing porn (ha ha) I could not help but give a schoolboyish smirk at the Pornstar Laundry sign. Nearly as funny as the Pattaya bar sign which proclaims "Liquor in the front, Poker in the rear"...
