During the height of football hooliganism, trouble flared up between the sets of fans. In 1998, during a match at the County Ground, 19 Swindon supporters were arrested, while in 2002 there was an incident between supporters after Oxford fans returned from an away fixture. In 2011, vandals burned the initials STFC into the Kassam Stadium's pitch. Oxford fans use nicknames when talking about Swindon such as moonraker, in reference to the myth that they tried to rake the reflection of the moon out of a pond. The rivalry with Reading was heightened during the chairmanship of Robert Maxwell, because of his desire to merge the two clubs. This was met with strong opposition from both sets of fans, with United supporters staging a "sit-in" on the pitch before a game against Wigan in protest. Despite being the second team in the city, there is less rivalry with Oxford City because of their lower position in the pyramid system (there have been no competitive league matches between the two since 1959).
