Correct way to report griefing?
Define griefing, please. If it’s WvW JP griefing there isn’t anything you can do about it but wait them out or gather a force large enough to overcome the griefers.
WvW JP griefing isn’t griefing. It’s a PvP tactic in a PvP zone.
Umm no this was PvE griefing. I just kill anyone that gets in my way in WvW.
Non-guild member followed us into our guild puzzle, stole a battery and jumped on top of the puzzle until the timer ran out so that we failed the puzzle.
There didn’t seem to be an appropriate category for this kind of harassment however.
One of the ways that you can report (PvE) griefing is to send an email to ANet support. Be clear describing the problem, include details regarding server, time, etcetera, and have screenshots.
Good luck with that.
And I am sorry you experienced that situation.
