I've said this before to people,
I believe online "gaming" allows minimal expression, only text and images.
Notice how your negs were unaccompanied by anything else within their "posts" therefore standing out like a red balloon. The repetition also shows intent, digging away.
Also, they were not complimenting enough, play with them. I have made this mistake in person really bad, simple said to this girl "are you anorexic?" the outcome was...hmm "bad"?.
The thing is before you even get to the neg stage you need to establish with yourself, why you are talking to her.
"Because shes an HB?" (X presses the buzzer) eeeRRRReeeeRRRR!!!
Wrong!
Forget she is good looking, what can she DO for you, literally.
When you take things slightly off the personal side, you can keep the string out of her reach but close enough to annoy her.
My example, on facebook, this model added me, when I asked her who she was she was all like " i wanted to poke you but i thought id just add you and say hi

" Probably expecting some afc response, OR genuinely fancies me, for safety I assumed the former.
Before shes even had the chance to go personal with me, I take it to the fact that she is also a photographer, I tell her that I am going to apply to modeling agencies. I'm in the process of arranging to meet her, so she can take snaps of me at her house for the applications.. -SHE HAS A USE!! A skill, a purpose-
That girl, Lennon, knows/thinks you are taking the time out to talk to her for her LOOKS, and you find her "special" (In her mind) or are AFC'ing yourself. With your negs you took it straight to LOOKS also, showing the area focused on
She got a purpose you can exploit? put the focus on the purpose. think of it slightly similar to giving her friends the attention in the club for her jealousy, take the heat off HER and put it on WHAT she can do for you! , she may even qualify herself if all goes well.
You are the prize! YOU are a man of value so this HB better be useful or sorry darling but your taking up my precious alpha time! Tick Tock!
