I think the incest phenomenon in porn was forced.
I personally don't read the titles and just base my clicks off of the appearance of the woman in the thumbnail, and usually I have it on mute because I don't want to hear some dude huffing and puffing.
I know it's not real incest so the title honestly doesn't matter, but every time I click an incest vid, I get added to the "oh, this IP is into incest!" list. This started slowly and a long time ago, but I think most views of incest vids are just people who see a hot woman in the thumbnail and click it without really caring about the stupid title.
I tried oneko for a day and wow.. not my thing. Constant distraction and I didn't get much done that day, lol. Not recommended for the work computer at least.
