... the issue I, personally, have about the whole 'kin for fun' kinnie stuff is that I'm spiritual, I had past lives, I have these memories, so I get.. excited, happy when I think I found someone? I see the names of those I used to know, I wonder if they are from my canon, or maybe they're from another universe altogether, how much do we have in common, what was different for them - and then I find out, oh, huh, they're just. Messing around.
Taking the name of someone I used to know, and pretending. In another few months they'll drop it because they get bored, or have moved on to some other interest/fandom, or they just don't like the 'character' anymore.
It's... disheartening. I think I see someone, found someone, but. Not at all.
Do what you want, I guess. Twist words that were not meant to change their meaning, slide right on in with using them in a way that will surely confuse others who know their original meaning. Play pretend before dropping it when you lose interest, ditching people who's own personal beliefs, whether spiritual or otherwise, are more set in stone than yours.
It's fine. "Communities change." "It's not that deep."
