You gotta feel for the techs running adult sites. Used to be (maybe still is?) the bleeding edge of web tech. Payments, micro payments, video, advanced site search, content filtering, crypto,... I guess there is a lesson there, like "serving primal urges = $$$". But you never see those resumes on linkedin.
That said, the peak I've pulled down as a SRE is a total comp of CAD$600k a year and I'm presently a CTO of a barely-in-the-media startup.
I'm doing ok.
