I was part of original /jp/. I was a Touhou shitposter on /a/ before there was a /jp/. I was there on day 0 when moot created the containment board.
I stayed for four years. But then the summer of the third year, too many summerfags inundated the board with their shit. The culture of /jp/ shifted too far, and I was left an outcast. I stuck around for another year, but there was no going back.
Sometimes I read through old threads from 2008-2011 on /ghost/.
