Some of this has been said already but here's my take.
1) How do you define 'black'? If you're including people like me - who are part black, and thus really are of 'various' ethnicities - then there's your answer right there. Lots of people don't like the one drop rule (particularly outside of the US, as far as I'm aware) so if that's what you're going by then that's it.
2a) Race fetishes. I'm getting this vibe off you if I'm honest... lots of ""cocoa women"" will tell you they actually don't really like being compared to foodstuffs. Just like AerynShade said. The very least you can do is say they have a skin tone like cocoa. that's just super weird saying they are a particular food.
Race fetishes come in all different forms... being assumed to be "exotic" or a stereotype, weird race-based roleplaying... all sorts. A few examples I've either seen or experienced:
- a guy once came into my room and said 'you looked Asian in your profile pic, but now you look black.' Only thing he said. It instantly gave the impression that he was looking for someone who would act a certain way to fuel an Asian fetish, and then when he saw I wasn't totally Asian he thought I'd be too loud and brash like the black stereotype. I don't know. But it wasn't nice or relevant. Also, you can be black and Asian...
- I think the first member I ever banned was someone who came to my room during a cumshow and said 'mmmm I love me some teen n****r pussy.' Even if we ignore the obvious choice of words that's still really gross.
- I was once talking to a member who started off nice, then asked what my heritage was, which I don't mind. Next question was 'how many languages do you speak? And don't say just English!!' and I just left the conversation. Again, it's making the assumption that I fit this stereotype of the 'exotic' mixed girl and leaves no room for me to be an actual individual. I think in this case he may not have meant it to be offensive, but it is, and at that time I didn't have the energy to explain that.
- assuming I can/want to twerk right up in the cam because apparently that's what all the hip hop video girls do
- etc etc etc... this without going into the fetishes for other races than black.
2b) Outright racists. I have heard from white models that they've occasionally had messages from guys saying how nice it is to 'find a hot WHITE girl!!' and I've heard the same thing from a white-passing (but actually mixed race) model. I've heard from other non-white models about guys coming into their rooms just to throw slurs at them. There are always going to be the assholes who just want to piss someone off. I don't know why you'd have to want to spend your time looking for people to insult for whatever reason... but people do, and for them it's a lot easier if all they need to do is type in a search.
3) The "I'm just not into black girls" crowd. Which is actually most of our target audience (ie Western straight guys). We're all conditioned to see black people as less attractive - that's why 'ebony' is now considered a fetish. Because it's 'taboo.' It shouldn't be, and a lot of people do know this, but it's difficult to unlearn old habits. I never used to be attracted to black/part-black people until I started to actually look into why I thought like that and tried to actively challenge it (which is also why I believe it's very rare for someone to genuinely not be attracted to x race, when all social conditioning is removed). There are probably a lot of members who remove the black checkbox from their list of models showing. Personally I've experimented with this a little... I'm a bit of a lot of things so I could technically say a lot of those checkboxes. I wouldn't say I'm white because [the one drop rule/the racists in 2b]; but I have had my ethnicity set as 'various,' 'black,' 'Asian,' and 'not specified.' I got the most traffic when I had it set to Asian - that's another kind of fetish that's also pretty gross but plays out differently to the black fetish. I didn't get as much when I had it set to black, and what I did get was mostly the black fetish types who wanted a stereotype. I keep it at 'various' now because that's the true one anyway, but that's why I don't blame the other models for changing it. I have seen a lot of black models listing themselves as Asian and I feel like it's sad but this is exactly why.
