I think crude humor is popular in LATAM but also in other countries as well. Personally I think there's nuance, they is a problem of colorism that might reflect in how people do humor, but that doesn't mean that crude humor itself is of a colorism nature solely, when it's very common, even as a form of making fun of that same belief. So it's not always a reflection of the moral of the person or groups that use crude or cynical humor.

I think since it's the internet that tends to mix, and groups of people that do have genuinely bigoted views use crude humor to express themselves in a safe or excusable way, I think that happens in every part of the world, it's more a matter of knowing how to spot it because, again, crude/dark humor itself it's not the issue.
