I think "NSFW" is much stricter than "explicit" though. I've labelled things NSFW that were basically PG rated, because they showed two guys cuddling in bed with naked chests, which is an image many would not want on their computer screen at work (unless I guess if you worked at that US banking oversight place who had these porn habit troubles while the world economy collapsed, then it would be tame... *g*)

The warning I was considering these for were of non-con variety, because of the slavefic aspect, because many slavefic pictures are typically visualized with collars and bondage stuff, that looks the same as consensual, and I wanted to get a clearer sensehow the picture and its contexts are to be weighed.
