Kingpin was an official group ran by members, which was purchased by V for Vendetta. The group had no user-bar but instead had a bolder username. The group was originally named Sheepgang before V for Vendetta purchased it.
V for Vendetta purchased Sheepgang and renamed it to Kingpin. The member-owned group was the only group to have absolutely no user-bar, banner or any other kind of graphics associated with it. Although the group seemed modest in having no graphics, it did boast a bolder username.
