nuotm=New User of The Month
Introduction
New User of The Month is a badge that discourse grants to users with “outstanding contributions in their first month” but, this badge is very rigged.
Here is the code that discourse runs to grant nuotm
If you can't access that
# frozen_string_literal: true
module Jobs
class GrantNewUserOfTheMonthBadges < ::Jobs::Scheduled
every 1.day
MAX_AWARDED = 2

previous_month_beginning = 1.month.ago.beginning_of_month
previous_month_end = 1.month.ago.end_of_month
if UserBadge.where(
"badge_id = ? AND granted_at BETWEEN ? AND ?",
badge.id,
previous_month_beginning,
Time.zone.now,
).exists?
return
end
scores(previous_month_beginning, previous_month_end).each do |user_id, score|
# Don't bother awarding to users who haven't received any likes
if score > 0.0
user = User.find(user_id)
if user.badges.where(id: Badge::NewUserOfTheMonth).blank?

Now, look at this user
0 likes received, 0 given, 0 posts created
And they got nuotm.
In the code there is this:
“Don’t bother awarding to users who haven’t received any likes”
Hmm…
[WIP, adding more soon]
