Don't confuse bad news with bad traffic or bad metrics. I'm willing to be Reddit has seen far more traffic benefits from their "scandals" than they may have ever lost due to "boycotts" of them allowing sometning on the site. I'm also willing to bet the so-called "pressure" from advertisers to appear more mainstream is far less of a financial threat for Reddit than people are making it out to be.

This is particularly true when you consider that NSFW sub-reddits almost never make it to the front page, where the presence of offensive content could threaten traffic.
