I was looking at one of the examples on the Arabic Language proposal, I noticed a user and clicked on him/her to look at their profile, on there I noticed he/she were following the proposal I reopened (StackOverflow (in Arabic)) but the follower count only says one (me). Is this a bug? or is it that this user followed the un-followed the proposal and his profile isn't updated?
That user has 101 reputation points from an association bonus; and as you get 50 reputation points if you confirm your email address on Area 51, we can be sure that he didn't.
After a quick look at other unconfirmed (101 or 1 rep) users who committed to/followed a proposal, it looks like unconfirmed users aren't included in the list of committers/followers.
