I don't know the history of the url but I'm guessing it's because:

1. It's like every other highly sought after url, it's short and it's one word
2. I know a lot of individuals who go for that kind of "holy, pure, angelic"(?) aesthetic (I'm sure I can name it differently, I just woke up)
3. A lot of people want it just for the sake of messing with others, unironically
4. I'm sure something or someone in the past has to do with it, but then again, I don't know it's history as I've said, so. Shrug -☂️
