Can someone explain why I am seeing the Threads post on the left rendered in that way until I click it, which then reveals the content (on right)? I’ve never seen this behavior on any platform.

Dunno about threads, but Discord does this if you mark text as Spoilers.

That makes some sense but I’ve never seen the feature and I certainly didn’t expect to see it on threads
@shoq @ralfmaximus It's also pretty similar to the blur effect in MFM (Misskey, Sharkey, Firefish etc), which "clears up" the text when you hover over it.
@shoq @ralfmaximus but also, in principle, I don't think it's that different from Content Warnings in fedi. Just served in a different way.

@panos @shoq

I like this approach because (unlike CW) you can read the whole thing maybe except for the spoilerly bit. Maybe only one or two words out of a post might be spoilers.

Two mechanisms to do similar things is very nice. Both can happily coexist.
