I posted a link to an online game I made in the comments here once, and immediately got all kinds of good and bad traffic.

Some people liked my work, found me on LinkedIn and sent a connection with a positive message. Other people tried every which way to SQL inject or attack the site, posted slurs in every available input, etc.

Someone copied the site and hosted their own version with a couple minor changes. I only found that one because they had left one of the links in, which gave me referring traffic from their copy.

All that from one HN comment, very much pre-AI too, not to mention the standard daily slew of requests probing for what I assume are known vulnerabilities in Wordpress or PHP.

The internet is a floodgate of different actors, many of which are automated, and a link posted somewhere like HN opens the valve especially wide.
