I can't remember if I've already mentioned it on here before, but I just added SSL to it, so it's worth mentioning again!
Earlier this year, I made RedFlag (https://redflag.ga) to help flag sites that you want to share but that might have some stuff people might not want to see.
There's a long, searchable list of warnings that you can attach to a URL, and if you share the URL that RedFlag generates, then people will get the warnings you added!
@dmoonfire That's true, but whoever created the RedFlag did it because someone who might see a post might not want to see that, not for the people who don't care. It's just one extra click for that person who doesn't care, and I'd rather add features for people who do care than for those who don't., y'know?
