Remember /r/coontown on reddit? My intention with that (as one of its founders) was to have it banned for what it said and not what it did, which was a huge success. It was to have guys like you see what the left really is about.

In the announcement thread for its banning, I suspect reddit went back to it months or years and edited the vote totals to hide the comments of people who were upset with the censorship.

Of course, having people aware of black crime statistics, even in a crude manner, was useful too.
