In August 2015, 8chan was delisted from Google search results. After a long time, we were silently reinstated, but we are still buried in the results by manually-adjusted algorithmic weights.
Christopher Poole [moot] quit 4chan in January 2015 and became a Google employee (circa March 2016).
4chan uses Google's reCAPTCHA (hint: tracking system) to this day.
Food for thought.
