When I was in college, my then girlfriend texted me that she was watching Jojo Rabbit. She knew it was one of my favorite movies, and said that she loved it too. She was talking about how Scarlett Johannson’s shoes almost have their own personality. So I said,
spoiler
yeah, it’s devastating when you notice her shoes on the hanging body.
Turns out she had paused the movie to make some dinner, and hadn’t seen this part yet. Needless to say, she was PISSED!
On mobile Firefox browser, I see everything, and in fact I’ve never not seen everything. So yeah, I’m pretty sure that spoiler tags don’t work on Kbin, at least via mobile browser.
Clicking over to https://lemmy.sdf.org/post/5881116, the spoiler section is properly hidden, so the same mobile browser works just fine on Lemmy.
Edit: and I confirm that I also see the spoiler text on desktop Firefox as well. And Google Chrome too.
Or on desktop kbin.
