>>6168650He said that he still browsed it in his 2015 Q&A so it's a well formed habit. So I would guess that he still does. He also created a former admin capcode so that gives evidence that he didn't want to fully detach himself from 4chan. Finally He Sold the site due to financial troubles not because he didn't like the website. This leads me to the conclusion that he still browses 4chan
