Is your name supposed to be read as copper sulfate? If yes, why did you choose specifically that as your username?
It is! There's a bunch of reasons: because the crystals have one of the most beautiful blue hues I've ever seen and I'm quite a magpie when it comes to shiny things
Also, CuSO4 is a +18 alter ego of mine, so I wanted the handle to be something related to forbidden, poisonous, unholy or just dirty. I ended up choosing concepts like mácula (taint, blemish) but then I had a look at my little rock collection and there it was, the deathly azure sparkle between the bismuth and the pyrite. And lastly, in Japanese, the word くそ (kuso) is an insult or a way of demeaning something or somebody.
So yeah, found something that checks most of the boxes :D
