Wikipedia editors have noticed that people use wikipedia for this purpose (finding the current location of sites) and so they have started to censor links for sites they don't want to encourage people to access. Right now this mostly impacts sites few would condone, like 8chan or kiwifarms. But in theory the policy applies to any site with illegal material so places like the pirate bay or scihub could have their links removed at any time.
Here's a well-reasoned argument linked from that thread for keeping extremist URL in articles about extremist websites. Strange what can change in just a couple of years.
Ah, the ever expanding definition of extremism. By now it already means anything that isn't politically correct. Organize terrorist attacks? I bet it's just protests they don't like. Lots of protests going on in my country right now and it's really tiresome to watch the media call them terrorists. It's like they all use the same arguments to silence and censor people.
Wikipedia has helped me in a couple of instances in which Google or DuckDuckGo couldn't, for example getting the latest onion or clearnet URL for a certain site.
Arguably the onion URL is information of value, but someone who can't figure out what the URL for 8chan might be probably doesn't need to go there anyway.
They certainly are no better than Google in that respect. Wikipedia has been censoring and promoting tilted political edits to the pages of certain figures for years now. Unbeknownst to most people, Wikipedia is central to the global censorship apparatus that's been put in place in the last decade or so.
I wonder if Wikipedia could take an approach similar to what package managers do in Linux distros when they decide not to include non-free packages by default: savvy users must add external repositories containing the banned entities (with such a repository possibly being unofficial and externally hosted).
Perhaps this could be realized by letting logged in users fill out a field for sources of third-party domain records, each of which could be a source of domains across the entire Wikipedia site. Or, more simply, just flag certain domains as such, and silently require users enable something like HN's "showdead" bit.
Otherwise, if you look at the size of that talk page, trying to decide this once and for all brings to mind the idea that "hard cases make bad law".
