If the history of the internet is to be any guide, it won't be the slog of racism that will shut something like this down, it will be a firehose of penis pictures.
Somewhere, someone will figure out how to create a bot that floods this with penis pictures, and that will be the end of it (or the beginning of the end, where a short period of anti-penis-pic defensive patches will be made until the software maintainers just give up)
There are people so worthless that the only reason not to put them between 2 buns instead of Bessie the cow is how disgusting they are. We are morally obliged to respect their human rights we aren't obligated to listen to them.
