So, do you dislike the Nazi bar newsletter site and want to know when some innocent looking link is going there? Here's some CSS for you, which you can add to an extension such as StylusΒΉ:
a[href*="substack.com"]::after {
content: " [SUBSTACK]";
font-weight: bolder;
}
Modifications of the text are up to you, such as inclusion of the emoji of your choice. You can also use more aggressive CSS if you want, there's probably a way to make the <a> disappear.
