You can't even search for GitHub issues anymore. You'll get some mirrored site that has the discussion, and from that webpage, you can't even get a direct link back to GitHub.
Unfortunately DDG isn't much better.
It takes a lot of effort to finesse a search query such that I can get a good result, like a link to documentation or a personal website where someone wrote something up (which is often more thoughtful than what Medium and Dev.to offer).
1. Search for something 2. See the cloned issue but no results for the original 3. Copy some unique-looking text from the clone 4. Search the repo directly for that text
It's awful. Seems to be a very recent problem? Maybe the last few months?

But this blocks it:
https://raw.githubusercontent.com/arosh/ublacklist-stackover...
https://github-wiki-see.page/m/entropia/tip-toi-reveng/wiki/...
higher than the actual GitHub wiki that all of the content was copied from
https://github.com/entropia/tip-toi-reveng/wiki/Languages
BTW, building my own interactive book was a great thing to do over Christmas.
I just don't understand why Google themselves allows this and doesn't rank these sorts of sites lower. They're clearly garbage sites with low utility.
It has already recently convinced/defrosted GitHub to gradually change their policy to not let GitHub wiki pages be indexed since 2012. For at least 9 years, people were writing content into GitHub and not realizing it wasn't indexed at all.
I'm happy to answer any questions or suggestions you have.
Unfortunately with smaller sites, it could be a few days till their search bot finds the content, and often the copycat sites have agressive scrapers so appear to have the content first.
From googles point of view, the copycat is the original, and the original is the copycat.
There are also some kinds of copycat content which users actually prefer. For example, sites which bypass paywalls, sites which quote other sites, sites that display decrapified content from another site, etc.
FWIW, GitHub seems to be letting some Wikis be indexed on a test basis and I am very happy to see they are outranking GHWSEE. That said, with the current guessed criteria, there are still many publicly editable wikis with many stars and publically un-editable wikis on repos with few stars but useful information out there that aren't being indexed.
GitHub blocks https://github.com/entropia/tip-toi-reveng/wiki/Languages and many other wikis from being indexed. In the case of the page you linked, GitHub serves the content with "X-Robots-Tag: none". The content of that page currently does not exist in Google at all. You can see the robot blocking header by looking at the Network tab in Chrome while loading the page in incognito mode or equivalent in other browsers.
As for having no link to GitHub, my service provides a huge button at the top and a direct URL to the original content. Please use those controls at the top to get to the content on GitHub. I do not selectively redirect to not trip cloaking detection or automatically redirect which risks the indexing helper being classified as a redirect in search engines.
If you have any other questions or suggestions, please let me know.
GitHub Wiki Search Engine Enablement (GHWSEE) allows non-indexed GitHub Wikis to be indexed by search engines.
This site will be decommissioned to redirect old links once the block is lifted or GitHub produces some other solution to index GitHub Wikis in harmony with their SEO concerns.
I do not see any wrongdoing from github-wiki-see.page here. They don't even amke money from it. Quite contrary, I do think that this is a useful project.
