Citizen Patrol has this description:
First flagged post.
In other words, anyone who flags anything for any reason gets this badge.
Making people familiar with the flagging function is probably the main point of the badge
This seems a little off to me. The flagging function is no more visible due to the existence of the badge, and I would much rather see users being encouraged to flag well instead of just flagging. I just noticed a user who got the badge after flagging his own post to spout nonsense, and the fact that it was a bad flag and got declined was obviously not taken into account.
I propose a new mechanism for Citizen Patrol to encourage good flags, made clear through a description like the following:
First helpful flag.
I don't think this would decrease the likelihood that someone who sees the badge will try to get it, and if it did it would only eliminate the people who raise a worthless flag. Win-win?
