Marcie, I'm writing this, not because I think we're ever going to be friends or pals or whatever. We're way too different, and we would kill eachother with our political leanings.
But, I was just reading your article entitled "What a Waste", and one thing struck me. You are accusing Sabrina of questioning, more like declaring that your credentials are not real; that you maybe are not the person you claim to be. She did the same thing to me on a number of occasions. She called me a liar about my age. Then, she called me a liar about my profession. When I raised the issue, she backtracks and says she was just 'questioning" them, as she "remembered" something else. What crap. she takes pleasure in tearing people down. it's what she does. She does it skillfully, as to just skirt the TOS, so that admins look the other way. Then, by retaliating, I called her on it, using aptly descriptive language for what I believe her to be, at which point, I got grounded.
She's really a royal b*****. But, you're feeding into her psychotic nature. Let it go. Give her a wide berth. Don't let her comment on your blog, and don't comment on hers. You see, she doesn't blacklist anyone, then baits them to retaliate to her dispiccable behavior against them. I tried to skirt around her. I really did. But, I finally succumbed to her nastiness and her baiting, and it got me banished from the forums.
Did I learn my lesson. Well, it depends what the lesson is. I learned that she's a skillful psychotic, manipulative low-life piece of trash. I learned that the admins seem to like her. I learned that the admins seem to not like me. I really don't care.
I guess my point, yet again, is to stop responding to her crap. It will die down, and you are who you are, and you know that nothing she says will affect that. I'm sure your self asteem is not predicated on whether the B likes you, or not. Move on. Give it rest. Stop stressing. It's not healthy. And, it just serves to lower yourself to her level.
