Some are.

Also I'm pretty sure the real reason is because there aren't many rules/regulations when it comes to posting pornography on there. Kinda like Twitter or DeviantArt in a way.

I've seen some on there, but didn't think it was any more known for porn than Twitter is tbh.

I'll test your theory though. Research purposes.

The truth is artists (especially Internet-based ones) like drawing porn and/or draw porn as their main source of income. Porn-based commissions tend to be what draws in a lot of money for budding artists where in any other scenario they'd be in the ruts. It's also why a lot of freelance animators have a background in porn- because it usually earns them more than any other work they could do, especially as sites like Youtube have algorithms that don't effectively popularize and monetize their work.

Tumblr is one of the biggest art bazaars on the internet, happens to be very popular, and has minimal content restrictions. It's a veritable breeding ground for porn.
