Exactly. Those are open redirects, and they've been disabled. See this recent PMD as well: PerlMonks Shortcuts in Other ChatterBox Clients

The issue I raised isn't about /?node=scheme://..., it's about the search box no longer functioning. These are two different things.

The search box currently makes a request of the form /?node=..., but it doesn't need to. For example, it could make a POST request.

Alternatively, it could continue to make the same request, but only accept doc://, mod://, id:// and other safe schemes.

You should maybe explain the benefit of such a feature, if you want it to be (re)implemented.

In 13 years here I've never used this.

The resources of pmdevs are limited and the to-do list is long.

The relevant part is:

I was curious how many spammers actually succeeded to post porn links in the monastery, so I ran a site search on google

porn site:perlmonks.org

to my big surprise I got plenty of hits from spammers using an automatic redirection from PM to their sites

What's happening is that links of the form

https://perlmonks.org/?node=http://spammer.com

are automatically redirected.

and that's what the searchbox basically does, it puts any searchterm after the ?node= and then our scheme://queries (including http:// ) were translated.

That's why the gods decided to disable this feature, any link-format will now only be searched verbatim.

Thank you. By the way, I am of the opinion that it would have been better to leave the feature enabled generally, and just disallow ^http redirects.

I agree.
