Yes, it happens. The notice gives a link to GitHub&#x27;s policy. A search of HN&#x27;s history ( <a href="https:&#x2F;&#x2F;hn.algolia.com&#x2F;?query=DMCA%20%20GitHub&amp;sort=byDate&amp;dateRange=all&amp;type=story&amp;storyText=false&amp;prefix&amp;page=0" rel="nofollow">https:&#x2F;&#x2F;hn.algolia.com&#x2F;?query=DMCA%20%20GitHub&amp;sort=byDate&amp;d...</a> ) shows previous examples of DMCA takedowns on GitHub.<p>One of those previous examples is titled &quot;DMCA notice against oh-my-fish&quot;. You&#x27;ll note that this submission points to oh-my-fish&#x27;s account on GitHub. Perhaps some of the 76 comments at <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10271304" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10271304</a> might be relevant.<p>Beyond that, I don&#x27;t know the reason for why this submission is interesting enough to draw the attention of HN readers.
