If you don't like how someone is acting on the forums, don't make a thread that's reporting them. That just starts useless flame flights. The "Report Player/Abuse" section is for in-game stuff only.
On the top right of posts, there is an upside down triangle with an exclamation point on it - click that to report posts/people. It takes 3 warnings (usually) for someone to get banned, so just because they are still posting after you report them doesn't mean they didn't get a warning.
Thanks
