This morning I stumbled onto this... all three have the same name, not sure what to make of it unless there's some power to duplicate yourself I'm unaware of...
My thought is that it is three different players, each with creative use of the similarity in-game of lower case L's and capital I's. Those two letters look the same in-game, so it would be easy to make a couple or so characters that appear to have the same name, but the spelling is different. You should have asked.
