I agree, I just had to downvote someone's post who just spammed that link underneath my recent post. Feels bad when people are just using the copy paste spam. :( I also think if folks are trying to without a reason attack you on a personal level (when it's not based on any truth) You should be able to defend your reputation like you said. And knowing you, I think you were right to do so.
You are helping so many people with a kind of energy I could never put forth.
