What's the point? The browser is still downloading the NSFW content either way, and gonna get red flagged by any content filter worth a shit. Hiding it behind a NSFW tag isn't going to prevent it from being downloaded by the browser and "It was behind NSFW tags" isn't going to be a valid defense when facing an angry boss. At best it's going to lull people into a false sense of security. Make a separate thread if you're truly worried about SFW stuff.
