OK, controversial but… If the text is written so well that you cannot tell it is AI and it actually relates to your interest, how is it a bad thing? The author would have never caught on if they did not see that blog post. I understand reading that you feel “tricked” but if they never saw that blog post then what? And if you are getting those mails at a rate of 100 per hour, then I can see the point, since its spam. But you had spam way before AI.
