After around two months of trying to get Deviantart to work with me, they finally responded the way they should have in the beginning.

DomiKnitrix had a picture posted of me in her deviations, and after AmeHisakataMizu and myself both requested her to take it down, she refused. I messaged her, and she failed to reply. Instead, she wrote a blog on her page depicting AmeHisakataMizu and myself as something akin to internet stalkers, and then made comments about going to the local police about getting a restraining order of sorts.

However, Deviantart has finally done the right thing, and taken the deviation with me in it down, due to the fact that DomiKnitrix doesn't have a "Model Release Form" from me.

*thumbs up*

Great success.
