BibTeX entry

 @misc{ wiki:xxx,
   author = "Citizendium",
   title = "CAPTCHA --- Citizendium{,} ",
   year = "2024",
   url = "https://citizendium.org/wiki/index.php?title=CAPTCHA&oldid=965331",
   note = "[Online; accessed 17-July-2025]"
 }

When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred: 

 @misc{ wiki:xxx,
   author = "Citizendium",
   title = "CAPTCHA --- Citizendium{,} ",
   year = "2024",
   url = "\url{https://citizendium.org/wiki/index.php?title=CAPTCHA&oldid=965331}",
   note = "[Online; accessed 17-July-2025]"
 }
