You are confronted to a Ass Hat. He is not a Black Hat SEO.
A Ass Hat will use techniques that put people’s jobs at risk. A Ass Hat will do Black Hat SEO unknowingly. A Ass Hat SEO will pretend to follow Google’s Guidelines while playing dirty in secret.
Stay away from a Ass Hat.
A true Black Hat SEO can’t be compared to a Ass Hat.
White Hat SEO doesn’t exist. Maybe it exists, but following Google’s Guidelines works for the Top 0.1% of the pyramid of content producers. The rest of us need some help to get results.
