I don't register on "news" sites because spam almost always follows after the site is hacked, a moonlighting employee harvests and sells the list, or a marketing type feels that the list is a pot of gold to be rented out. In any case the result is wasted time for me as I wade through the trash. Sure, I have a very aggressive filter that can block the trash, but every time my address is shared it likely starts chain of shares, each requiring some of my time to wade through and push back.

Further, many of these "news" sites insist on sending daily updates.

Finally, the "news" organization may use a free platform that is in the business of compiling lists and sending emails that "may interest the registrant". (read the TOS)
