I have a very personal list in 3 categories. Category 1: Women who do it just for the money and are terrible at acting (I find these videos boring). Category 2: Women who do it just for the money but manage to pretend they are enjoying it (depending on the scene, it is something that turns them on). Category 3: Women who do it for the money and love what they are doing, take it seriously (it makes it a real match). In this category 3 I use a very personal criterion. No kissing!!! If there is kissing, for me it clearly becomes sex and not fighting, and I have only seen a few women having matches without wanting to kiss the other and instead attacking them, I have only seen a few:
1 - Amber (Chickfight)
2 - Ingrid (Tribgirls/Foxycombat)
3 - Joslyn (Chickfight)
4 - Emanuella (Tribgirls)
