Just stepping in here to say that griefing/disrupting of RP events can be reported, but often, especially when the queues are long, it can be difficult to verify after the disruption has ended.
Inappropriate content in public channels (including addons) should always be reported via the ingame “report” function. Customer Support can review the logs for these and action accordingly.
However, the forums are not a place for naming and shaming and action will be taken if they are used as such.
