The report suggests that in prior years, exemplars of assholery such as Stormysky or Chestwick hung around the MUD for years, entertaining, annoying and outraging people on the MUD through lengthy notes and protracted conversations on gossip. Eventually they would disappear altogether, either in an Imm-induced mushroom cloud, or perhaps the more subtle approach of hitting puberty, and would be heard from no more.
Nowadays however, suggests Professor Braxing Flangiatel of Aylor University, the turnover rate is much quicker.
"Characters can go from absolute nobodies to figures of infamy to absolute nobodies within a period of weeks, or even days," he announced in the keynote speech for his latest paper. "A textbook example would be the Character known as 'Lemon', who came screaming out of nowhere with his buffoonery, amused and irritated everyone who came It is uncertain as of yet as to whether the MUD will reach a 'twat horizon'into contact with him for a couple of weeks, and then disappeared off the face of the map entirely."
After these characters disappear up their own arseholes, asked one of the audience, have any of them ever returned to the public eye?
"We have no idea," replied Professor Flangiatel, "No-one even remembers their names. There was one, named after some sort of bird, Chaffinch or Swallow or something, but no-one cared enough to look back and check."
It is uncertain as of yet as to whether the MUD will reach a 'twat horizon', where the creation of a single character who instantly becomes famous and obscure at the exact same moment, effectively colliding with themselves in an explosive annihilation of energy.
"We can only hope," added the professor.
