Seems at best like a very insidious marketing ploy to me idk.
Liking a couple posts of a very particular fetish at odd hours every couple days when nobody notices except a couple of randos on lpsg (who don't even pay for porn let's be real lol) seems like the dumbest "marketing ploy" ever.
I still think the most likely explanation is that he has a humiliation/sissy/degradation fetish (which is the the type of porn he seems to like the most) and when he's horny he likes to "expose himself" (or just "save" some porn to cum). After he cums the post-nut clarity hits and he deletes everything cause he probably doesn't want himself so publicly attached to quite hardcore kink.
One time I saw him like a post of a woman joking about white men having small penises and another talking about withholding sex from white guys (not even in a fetish context). It's textbook sissy/humiliation fetish stuff. It's not something you even know about unless you're really into those kink circles.
