Thats actually one of two ways.
The + and - add or remove reputation points. A tally separate from actual points or post count.
Below is copy and paste fromt he forum rules.
If you notice a topic or poster in violation of these rules, please send a personal message to one of the Moderators, or use the report button in the top right corner of the message box (The image of 2 exclamation points), so the situation can be dealt with. Do not back seat mod and try to control the situation yourself. This too can be looked upon as trolling. The moderators of this forum have been doing this a while and are good at what they do. At the same time, no one person can be in every topic at all times. Do your part to help keep the community a positive environment.
Please utilize this report feature appropriately.
Spamming the report button with False Alarms will lead to bans
Please note: this report button is used for Nominating good posts AND Reporting Abuse. When you click it you will see at the top of the editing window a drop-down menu with three options:
* Nominate this post
* Report Abuse
* Misc. I can't think why we need a miscellaneous category as the only reason to press the button is to either nominate or snitch, but there you go.
Please choose the appropriate category and then type your reason for the report.
If it comes to a choice between being a good soldier and a good human being -- try to be a good human being
