Substack is the worst with this. I get 2 paragraphs into the article and obscured the text to prompt for my email. Like shit, I don't know if I want to subscribe yet, I haven't read the fucking article. Maybe if it is good I'll subscribe, don't try to trick me into it. I'll happily consider your subscript prompt after I have read the article and have an opinion on if I want to subscribe.

Now I just leave the page whenever I see that prompt and I've configured my browser to flag all substack links so that I don't waste my time clicking them. (Unfortunately it doesn't work for custom domains).
