M06, Welch/Moore cheap shots

In an earlier Proviso Probe discussion a supporter of Emanuel "Chris" Welch who reads campaign documents posted the letter about Fair Campaign Practices candidates are required to sign. This Welch suppporter was attempting to scold Rep. Karen Yarbrough by posting,

(1) I will conduct my campaign openly and publicly, and limit attacks on my opponent to legitimate challenges to his record.
(2) I will not use or permit the use of character defamation, whispering campaigns, libel, slander, or scurrilous attacks on any candidate or his personal or family life.
(7) I will immediately and publicly repudiate methods and tactics that may come from others that I have pledged not to use or condone. I shall take firm action against any subordinate who violates any provision of this Code or the laws governing elections.

But over at the blog set up to support Welch and attack his critics, this is what one Welch supporter wrote,

[State Representative Marlow Colvin is] Karen Yarbrough's lover according to sources. There are pictures to prove this, I am sure Henderson knows...

Can Welch explain how this rumor is a legitimate attack on Yarbrough's record?

Does Welch agree that spreading a rumor on a blog anonymously constitutes using a whisper campaign?

Does spreading unsourced allegations about infidelity count as a scurrilous attack?

Has Welch repudiated these attacks on Yarbrough?

Does Welch know who posted these attacks?

Email Emanuel "Chris" Welch, info@chriswelch2006.com, and ask him.
