Might be WAI but it is worth reporting. a) If you look at this post, it shows that "ragtek likes this." but upon clicking on ragtek it shows user not found error. b) If you click "2 others..." in this post those 2 others are missing. Might be deleted users as well, but seems confusing... if the a) as intended, why is those "deleted users" not showing? For some posts a simple "1 people like this" shows. Seems like different behavior due to a deleted user.
