I was just perusing the rule set you have implemented. I do not see a rule as to where a banned player cannot spec. I've seen it countless times in the past.
However, once yours truly does it, he gets banned from the server. Better yet - why don't you add a rule that no one can question an admin whilst while etching yourself in the book of ignorance. Or you can completely trample the freedom of speech entirely.
