[QUESTION, ANSWERED] Is there a rule against having more than one account?

[iHateAmpersands]

I'm curious because there's a thread I read on a semi-regular basis where I see two posters who I think might actually be the same person, as their posting styles are identical to each other. I don't see anything in the FAQ about it so I came here.

If members want to use multiple accounts that's a-ok, unusual, but a-ok.
