“Obsessed” isn’t a bunch of people responding to something you publicly wrote on a message board. “Obsessed” is looking at a poster’s profile, attempting to discern patterns based upon the number of posts they have read and the amount of time they’ve spent viewing the board, finding no pattern, and telling everyone to keep an eye on them anyway because… reasons?
I can’t even remember the last time I looked at someone’s profile, if I ever have.
