I hate to use Karen as an example here. However, as others have mentioned and alluded, I believe Karen's handle is simply stating her "affiliation" and "disclaimer."
I find it helpful when others, shoppers included, state similar disclaimers. Such as being deactivated by a MSC when further proceeding to discuss a MSC.
In edithms's case, it would be helpful for him/her to disclose, dare I say, "an axe to grind."
( Pardon my my cheekiness

Don't dish it, if you can't receive it, either. )
It is my opinion, a better and more relevant "analogy" could have been inserted.
Please don't feed the MSF trolls!
Feeding the MSF trolls bread or other human food is detrimental to their health and the environment. It can lead to malnutrition, disease, and behavioral problems in trolls, as well as water pollution and the spread of pests. Trolls are capable of finding their own food sources and don't require human assistance.
