S r (aka Oguz or oguzkan1200) is a Sparta Remixer who joined the Sparta Community in late 2012. Before being a Sparta Remixer, he joined YouTube on April 13th, 2009. He discovered Sparta Remixes on December 2nd, 2012. On March 20, 2013, his youtube account got closed.
So he used his alt channel called "oguzkan1200Alt2", which he created on February 28, 2013, 3 weeks before he got terminated.
He made a new channel titled "s r" in 2016 and has kept it since, until at the end of 2017 when he closed his youtube account without announcement or notice.
Sometime on or before October 2020, he reopened this same channel, however.
