I don't think changing "don't" to "do not" is what the paper authors had in mind I use things like "Your code should be self-documenting, so as to require as few comments as possible. Add comments to explain "why" or give important context not apparent from the code itself, but keep them to necessary comments only" But that's a much laxer rule. I don't think you can truly express "no comments, ever" without a "don't" rule.
