Weird Google Rules For Adult SEO. Any Thoughs?

In fact there's no rules at Adult niches. My best sites struggles for 1st pages and a helluva nonstop work. The ones I though they were was lost are coven writing quite good. Some of them not even are mobile-friendly.

Since BP got banned from USA from Adult Ads I'm having great results over there. Does anybody having the same results? Good and bad ones?
