If a user is the type of person to consecutively get downvoted to potential negative reputation, so be it. What's the reasoning to maintain a minimum of one?
One reason that may justify this is of trying to not deter new users from the site whom haven't read the FAQ and unknowingly and wrongly ask or answer a question. But most of us acknowledge this and not downvote in such a scenario.
So what's the reasoning behind this lower bound?
