I have a feeling Zen is not directly answering the question on purpose. If she lists out all of her detection techniques, someone will find a work around. There are a number of things you can do check to detect multis... There are web sites dedicated to it, and ebay has a whole team of people that do it for a living.

Same IP range/Proxy accounts can be different users, that is why there are probably multiple triggers for getting fed jailed... and why you have the option of mailing the admins to get it cleared up. If you think you might be at risk (same job, same family, etc) just mail Zen as soon as you sign up.

The point is, don't multi.. and if you are wrongly accused, just make your case and trust Zen and Err to the know the difference.
