Seems pretty easy to cause problems for other people with this.

If you follow the link at the end of my comment, you'll be flagged as an LLM.

You could put this in an img tag on a forum or similar and cause mischief.

Don't follow the link below:

https://www.owl.is/stick-och-brinn/

If you do follow that link, you can just clear cookies for the site to be unblocked.

If a legit user accesses the link through an <img> tag, the browser will send some telling headers. Accept: image/..., Sec-Fetch-Dest: image, etc.

You can also ignore requests with cross-origin referrers. Most LLM crawlers set the Referer header to a URL in the same origin. Any other origin should be treated as an attempted CSRF.

These refinements will probably go a long way toward reducing unintended side effects.

You do not have a meta refresh timer that will skip your entire comment and redirect to the good page in a fraction of a second too short for a person to react.

You also have not used <p hidden> to conceal the paragraph with the link from human eyes.
