There are some users who have really good observations and are interactive in comments, but don’t identify. Maybe the logic should be 100 observations or identifications?
Or better yet, activity level? I think “Duress” and “Contest” users are active for a very small window, maybe 3 months or less, whereas regular users stay on for 6 months or more? So maybe don’t allow opt out until user’s account has been active(open?) for 6 months?
