Indeed! Just one example in /r/Diablo_2_Resurrected/ screenshots of very good, very rare items are marked NSFW because they're considered "disgustingly good" and because having to do an extra step to reveal the item provides a "rush" similar to gambling.
I often use spoiler formatting for comedic effect, etc.
It's a recurring joke in /r/AoE2 (Age of Empires II) to label screenshots of particularly aesthetic base/farming layouts as NSFW.
For context, normally you are placing 3x3 tile farms either around 2x2 tile mills or 4x4 tile Town Centers, so you end up with a "pinwheel" at best. But the Poles can build a 3x3 Folwark (like a mill but makes your food come in faster if the farms are close enough) leading to some very satisfying ways to use building space efficiently and aesthetically.
