Is there more context on these two specific points?
They ran with a guy that called himself "Lucifer Valentine" and did a lot of vomit porn with him. In one particular movie he'd coaxed a drug addict into the porn and the sisters were in charge of making her puke and playing in it. Valentine also believed he and his middle-functioning austistic sister were reincarnated Lovers. He ended up with custody of her after the parents died. She was abused by him, it's unknown of the Soskas were involved in that or not.
The sister killed herself after 8-or-so years of being his sex slave.
As for the pedo posting, they apparently traveled in what was called "The Rape Van" due to it being a white panel cargo van that was used to transport band equipment. While on their way to a shoot in the van, one of the sisters sees a set of twin boys and takes a picture, and then posts it with a sexually suggestive statement about the future the twin boys have.
To my knowledge all of this is before Eric July launched the Rippaverse. Lucifer Valentine, the porn, the sister, the drug addict, all of that was back in the early 2000s. 2008 or so. They were college age/fresh out of high school and seemed to want to piss off whoever raised them.
These days they're "Hot Topic Goths". If the term doesn't ring a bell, it's the fashion of Goth but the attitude of someone who is upbeat and happy. GINO (Goth In Name Only) didn't catch on, thankfully.
They were promoting a killer stripper nun book back in September of 2023. It features two half naked nuns in a Tarantino style shoot 'em up involving the nuns cutting the penises off of police officers.
I can't say if they're "reformed" Christians, or if they're half in half out.
All I can say is that
I don't have to explain their shit to Saint Peter at the pearly gates...
