I never felt there was much censorship or that I’m in danger on the Internet. Porn sites are banned, that’s about it. Saudis live on piracy, and piracy websites aren’t banned and very popular. On social media just mind your own business and don’t talk negatively about the royal family / government and you’re fine. Just use a VPN if you want to watch porn & feel extra safe. I don’t feel the need to use a VPN.
