Creepy as hell. The club room my university's mock trial team used had a note from the club's president from 2007 or so for future generations hanging on the wall and one day I decided to google her and she had a Key Wiki article. As far as I could tell she's not a public figure of any sort, just a random person who was in a DSA facebook group that these weirdos decided to catalog.
Generally speaking if you're in a DSA FB group you will have a keywiki article. I have one because I was part of my university's DSA fb group, despite never being an active member.
