I don't think that the engagement on NSFW is really any lower than normal during November. it's really largely a meme that I'm sure many don't actually take at all seriously. I think the most obvious example of that would be the fact that, in the furry community at least, it's used more as an excuse to do edging-themed content for a month more than anything else.

Good point. Maybe after I'm done with the image I'm working on I'll make something edging related.
