I keep getting results to a site 'gitmemory.com' which is just GitHub issues scraped. Super annoying that they outrank the actual GitHub issues they've taken the content from.
How is this not just spam and duplicate content. I remember when I was punished by G for duplicate content on my very small private blog when I was using jekyll and had the markdown sources and the code stored in GitHub. I didn't know of the canonical tag back than and was punished because the GitHub domain had more trust.
It is sad, bit nowadays I often just directly jump onto page 3 at Google or use other "tricks" to get okayish results.
