What do you think of people who have a lot of kins, or “high polykin”? I’m talking some people who have like 20, 30, 40 fictionkins and find themselves unable to seperate from most of them. Are they taking things too far or just more spiritual?

Depends entirely on the person, and their attitude towards being kin and how they see themselves. 

Generally speaking the larger the number of kintypes someone has, the more I want to know that they’re sincere and not just collecting, trolling, or mistaken. But its entirely possible for someone out there to recognize and value that many connections, mental, or especially, spiritual. There’s no reason to automatically disbelieve someone with a large number of kintypes based on that evidence alone.
