Keep in mind that a spammer would not have had time to write more than 5,000 posts, his account would previously be full of negative badges and probably the most striking of them, L.Q.P., additionally, that user would also be in the "Under Review" group. They are neutral because they are badges that are obtained as achievements unlocked on the forum. Think that the "super active" badge can be for a specific activity, we cannot write 25, or 50 posts every day, but sometimes it is possible.
I know that mister president
5000 posts was just an example, but I see some members posting only news article all the time, so it is not impossible to happen.
I like the badges here and they can be improved, maybe added few more.
A suggestion can be made to the administrator about what you say about the list.
Should I write this as separate suggestion, or president will inform admin, he has more power I think
