Nope, the Reddit admins just haven't closed those subreddits yet. But they will. They've closed the child porn subreddits, they've closed the revenge porn subreddits, they've closed the hate groups that bleed out into the larger internet. r/coontown will be closed, too. It hasn't yet, which is a shame, but if you read into that fact that the reddit admins approve of it, then be prepared to be disappointed in a few months when it gets closed, too.
