Is this campaign activity by TNDC (Yes on C) legal?

Hi All! Please take a look at the email below. Quite interesting. He has some specific questions that I wasn't sure what the correct answers are, though I already wrote him back a response of my impression of the whole matter. Please advise your thoughts on his experience and what the law has to say about it.

Thanks!
Aubrey

Hi Aubrey,

I would not give "tax advice" without a license! Maybe suggest he send his letter to Mayor Lee, with a copy to the Examiner?
