As the author is disclosing his identity - am I correct in not flagging this as SPAM?
Edit: the core of my question is if flagging as spam is appropriate - as this for example clearly states that spam is about commercial advertisement. The only reference to "survey == spam?" is an answer that says "flagged it as spam" - without giving any further arguments why that is appropriate.
Given the severe consequences of flagging as spam - I think a more canonical (argument based) answer is needed.
