10hp Purist - Many of your friends' posts do appear that they are negatively discussing another forumer. That does fall under flaming, and would cause those posts to be hidden. Your friend should not be engaging in that type of forum behavior.
Ultimately, it sounds like what you are bringing up here is something that is between your friend and Jagex. If your friend has posted on FMR, then it would be best for them to wait for a response there.
Mod Lee reviews FMR every Sunday evening/Monday morning. It has not yet been a week since then, so it is likely there will be a new post there within the next 24-48 hours.
There is little additional assistance that can be provided within the scope of the Forum Help thread with regards to this.
