This sounds crazy because it is an insane bug to me. But when I’m browsing porn, I know my phone has the silent button on and volume is at 0. I also know that I’m not actually pressing the volume button.
The ad will come on before the video and then go: “ATTENTION ARE YOU LOOKING FOR A BUDDY TO MASTURBATE WITH?”
How is this possible? Surely it is a bug? This isn’t an app, it’s just a website. One hint I got is that if I push the sleep button on the side then wake up my phone, it looks like it is playing a 30 second audio clip. If I reopen Safari, it starts playing again
