Right here:
You’re saying you want people “griefing” to be banned. So yes, you are asking for staff intervention. No, you weren’t trying to have a discussion.
The problem with “griefing” is it requires knowing what a person’s intent is for otherwise permissible behaviour. Blizzard’s staff cannot verify any of that from their logs, and this is the same reason that multiboxing is permissible; the in-game effect is unchanged. Blizzard only acts on things they can objectively verify and (if need be) falsify.
