I too host my sites manually. What happens when your site that's hosted on the VPS gets noticed by a trigger happy skiddie? What happens when they start eating up all your bandwidth? Your VPS provider will be more than happy to null route you.

For the websites you own, you registered your domain with someone right? What happens when that company decides to have some AI decide if you are doing something illegal?

Until today I "never had" any of these issues as well, the main issue here is we have to rely on large companies (or small companies for that matter tbh) to do "the right thing", and we don't have many options to solve it. I got super lucky some folks browsing HN decided to get my post some attention.
