thisissparta789789 is a Post-Return era troll who is mainly known for his splices, especially intro splices. Sparta has a much more hostile relation with Ghost than most trolls because of the content in some of his calls, which has lead to Ghost giving outright serious threats to him several times in the show.
He first listened to Ghost in 2012, just months after he stopped broadcasting. When Ghost came back in 2016, he at first lurked until around June 2016, when he began making calls. His first cans.wav call came from the intro splice "True Communist Radio" in Episode 302, which caused Ghost to rage for 9 minutes before ending the show.
In one episode, after playing a splice where the Engineer had sex with Ghost's granddaughter, Ghost began to take a more serious tone with his anger, telling him to "die in a fire." In Episode 369, after partially playing "True Incest Radio," Ghost revealed that Sparta was a volunteer firefighter, something he had told the BronyNetwork chatroom on YouTube when explaining why he was not often around on Mondays. He then told him to burn in flames and prayed to God for it to happen, and his voice even became demonic. Some of Ghost's lines during this rant proved to be premium splice material, especially the line, "Lol, you died, lol, lol, you died," which came to be used in many splices and remixes.
After the Kylecnj Incident, Sparta became one of several moderators on the BronyNetwork's livestream of the broadcast, but resigned in May of 2018.
During Episode 431, an intro splice calling out CelticBrony actually led Ghost to come to Celtic's aid and reveal that he's a part of the Inner Circle. Thisissparta789789 knew that Celtic was in the Inner Circle, but did not expect Ghost to defend him.
In May of 2018, Sparta was doxed over a correction he did after Ghost got the dates of the release of Rapture by Blondie and Rapper's Delight by Sugar Hill Gang wrong, and he was accused of being a Woody Allen Butt-Loving Pedophile. His doxing sparked fighting between the Official TCR Discord and other listeners of the show, as well as threats being sent by those who doxed him to people he knew outside of the show.
After Ghost started The Ghost Show in 2019, Thisissparta has started hosting a trolling stream on his YouTube channel.
