Hello 30-20:  I have a hypothetical question for you.  

Let's say someone writes a Letter to the Editor using, as required his or her actual name.  Then the person, posting anonymously on this site, becomes a "self-shill" and writes comments supporting the letter, going so far as to address the letter-writer in the "third person"...representing, of course, that he or she is NOT the author of the letter.  Were such a thing to happen, I'd consider it extremely tacky.  What do you think?   Thanks for an answer, I value your opinion on this interesting issue.
