Link w/ Comment - EDU site

I am trying to post a comment / link on an old archive site, people are actively adding their links on the site but everytime I try to do it I can't post the comment.

Any ideas on how to successfully post a comment?

Thank you.

just checked the target . honestly mate , ur likely fighting a ghost .
huge chunk of these cambridge/oxford subdomains moved to static html archiving years ago . the comment form html is still there in the dom , but the backend handler (the php/cgi script that actually processes the POST request) is often disconnected or 404
how to verify before u waste time :
open devtools (f12) -> network tab -> click submit .
if u see a 404 or 500 error on the request -> the endpoint is dead , move on .
if u see a 403 -> its a firewall/ip block (maybe akismet or cloudflare) , u might bypass it with a residential proxy and clean cookies .
my team dropped most of these .edu archives from our lists back in '23 . usually the active links u see are actually old injections from years ago that just stayed there when the site went static . dont confuse historical spam with active vulnerabilities .
