Be warned they can temp ban you from the forums for photos that display character names under the pretense of "shaming." You should remove that picture and instead describe what you see. Even if it's likely a legit report.

You can report this kind of thing in game so you should do it there, because they probably don't forward the reports from these boards. You're also able to give more detail with the form provided in game so it'll help them out in the investigation.
