I don’t think we do have a well documented rule forbidding it to have multiple accounts.
I don’t think we have well-documented rules, period. About the only explicit policy statements I can think of are the one forbidding advocation of violence and now the one interpreting block downvoting as harassment, and those were both posted as normal articles (and thus quickly buried). The FAQ talks about etiquette, but presents very few unequivocal guidelines.
There’s a couple other actually-enforced norms I can think of, like “don’t talk about the Thought-Experiment-That-Must-Not-Be-Named”, but those are even less explicit.
