Ok. Firstly, mass reporting will do nothing more than squelching the chat ability of the account, pending investigation by GM who will either overturn it and remove the squelch, or apply a penalty based on what they found and the history of any previous account action.
Secondly, what you were actioned for wouldn’t have been immediately prior to getting actioned. It takes time for the report to come to the front of the queue, and time for the investigation. This could be a week or more ago.
