I’ve ended up making two versions… one I consider “explicit” and the other “cleaner”, so think Unrated vs R MPAA movie ratings. This has been a success IMO, because I’ve also written a bit of software that lets me write the two versions in the same file, where I annotate what’s “clean” and what’s “explicit” – it filters it out and I post the results. Thus certain descriptions, scenes, themes, and characters (& implications) are in that explicit side only. Of course, this has now resulted in the explicit side being about three times the size of the clean…
