Unless someone makes a chr. with an idiotic stupid name to begin with, then later on regrets that they made their chr. seem like it was named by a moron, a name change may not be of much use otherwise. People are oft creatures of habits.
One can even see that here on the forums, someone may become banned they return with a new poster name, yet they carry the same spelling, punctuation or errors in spelling, same mentality, and friendships or same enemies, same habits same opinions etc. ....that they had as 'poster whomever'.
It does not take a rocket scientist to figure out whom they ARE/and thus whom they WERE, when they come back posting HERE even on a new name. It oft is the same with chr. name changes !
