How many images to qualify for a catagory?

lately alot of free sites are fucked up, they say anal category and i see 3 picks in anal, then they say group and i see one gallery group and one gallery couple and i can give you more examples, for me its all in the rejected category, more then 50% has to be pics of the niche you wanna submit too..........i think free site submitters should realy focus on the pics they wanna use for an category, and dont say what you know about it, i was a freaking free site submitter myself
