The suppression of Eli Banana in 1894 and of the Hot Feet/IMP Society in 1908 coincided with the rise of academic societies, including the semi-secret Raven Society, whose members are initiated in a secret ceremony but is otherwise public. At around the same time, the Seven Society, a group so secret that its members are not made known until their death, appeared. The Seven Society established a new model for secret society operation on Grounds. While the ribbon societies were observed to draw their membership from the fraternities, and the IMPs and Zs from the ribbon societies, the Seven Society's extreme secrecy meant that the society had no apparent formal connections to the social secret societies. At the same time, its exclusive focus on philanthropy meant that, unlike the Elis and Hot Feet, it functioned as an important contributor to the aims of the University. The Sevens tap not only student leaders, but also University administrators and high-profile personnel. They take their secrecy so seriously that they only tap individuals for membership at locations off Grounds. It has been suggested that the IMP Society is composed of the Sevens underlings. The other societies founded after 1905 likewise define themselves in relation to supporting the University, whether through recognizing notable or notorious individuals (P.U.M.P.K.I.N.s, 21 Society, Sons of Liberty) or upholding University traditions (Purple Shadows). The A.N.G.E.L.S. Society both reaches out to students who may be struggling or simply those who display kindness or other laudable characteristics.
