Interesting what’s written here, I actually saw it more often in some Discord server. As far as I know, there it is just for fun and/or homestuck nostalgia, without any deeper meaning behind it.

Just like calling X “twitter” or “the hellsite”, or annotating everything with parenthesis, or using or refusing to use emoji, there does not need to be more of a reason to do something with written language than “I like it that way”. How much stylisation you can inject into your writing before you stop being comprehensible is another question.
