Anyone can set up a website and share it with others
Not as simple as it used to be. Thanks to the abuse from ad, social media, and other tracking networks, now you need to comply with the cookie laws, personal information laws, data retention laws... and so on. It's no longer as simple as setting up a website and just sharing it; just having an uncontrolled log, or lacking one, can land you in trouble. Allow random users add content (like comments) to the site, and you can get drowned before even realizing what's happening.
