if i where to give anyone advice on how to make people believe you are not the person who you really are, especially if you have unique speech patterns or a interesting/proper vocabulary, its to change the way you talk. it is surprising what people can pick up from only the way one talks. also, its important not to bring up your pevious alts in any conversation... granted i do that frequently but only because i am good at hiding that that person is me. namely, i tend to subtly insult and criticize myself/my alt so that it doesn't look like i have any emotional ties to them... then i send somebody else in to terrorize the server or website under my name while i am active with my alt... this also removes suspicion.
