Your browser is suspiciously without a Sec-Fetch-Mode header

You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace, the wiki thing it's part of. Unfortunately you're using a browser (or client library) that my anti-crawler precautions consider suspicious because it's not sending a Sec-Fetch-Mode HTTP header while claiming to be Firefox or Chrome (both of which have been sending that header for a very long time), or another browser that similarly should be sending this header (such as versions of Safari and WebKit from early 2023 onward).

Due to the ongoing problems with abusive high volume crawlers using forged User-Agent values (apparently in part to gather data for LLM training), this combination of browser User-Agent and lack of Sec-Fetch-Mode header is not accepted.

If this is in error and you're using a current version of your browser of choice, you can contact me at my current place at the university (you should be able to work out the email address from that). If possible, please let me know what browser you're using and so on, ideally with its exactl User-Agent string.
