Everyone in this thread thus far is correct, except with maybe [member="Onix"] . I'll explain:
Onix said:
HOWEVER! You can not have them in the same thread as that would be considered Alt padding
You can, in IC threads. But only until it becomes offensive to another player and they report you. Then Staff will intervene and ask you not to, though this is hardly relevant because if you have multiple identities but only one character, he can't be in the same spot physically at two places, yadda yadda yadda.
We smile at imagination and creativity. We frown when another player becomes directly offended by the duplicity, and we will act if you are reported for it. It's certainly not a bannable/suspendable offense, if it was entirely by mistake, but we will get involved.
Though what Onix is referring to by mentioning "alt-padding" is likely in OOC threads. We ask that you only use one character per OOC thread to avoid confusion/alt-padding.
Alt-padding is defined by Staff as supporting your own opinion with a second character, or being generally duplicitous in nature OOC with a second (or more) account/character.
