Not at all. It's just to remind folks that NSFW can apply to things like politics, dark humor, religion, etc.
I don't download things to my phone, I'm retired, and I live alone, so I'm not worried about anybody seeing those kinds of things when I post them on FB, etc. But, for instance, I know that if my former boss--an incompetent narcissistic pathological liar sociopath with inherited money--had seen my political memes she would have been furious.
I'm a lawyer, so I'm pretty thick-skinned. One of the things that is EVERY lawyer's obligation is to foresee "worst-case scenarios" and warn people, even people who aren't clients.
In THAT regard, I've posted the following TEMPLATE, and the description includes a link to the details that I had previously sent to some sex stream mods.

As I mentioned in this thread--several times recently I've posted a death meme on FB and then remembered "Oops! My cousin!"
I didn't post the warning just in the Dark_Humour stream. The reason I added the (See comments) is because otherwise it would not have been featured because "not Dark Humor".
