No scripting or anything illegal. Though, he knows that he has a weird and uncommon skill not publically considered normal. Changing nicknames usually result in this as admins do not have background information of who you are. This can be interpreted 2 ways: Firstly, if anybody considers you are scripting but are unwary to ban you for it, you can change your nickname to check that out(this is somewhat a risk but ok). Secondly, it's not the fault of the administrators to ban you for a player doing something weird or uncommon. Since categorizing as cheat and advantageous comes from doing things that attract attention and seem out of place.
So your actions sector are double-sided. So it comes to the unban panel to decide what is your verdict.
