At the moment there are options for "Spam" and "Other" on the report screen. Could this be expanded? Maybe "Personal Abuse", "Troll", "Disagreeing With Tiggy", etc? Quicker for us in most cases and I'm sure it would be easier for you.
Since we have stopped getting personal replies to reports I have really cut down on reporting. Fed up of trying to guess whether what was posted had been looked at and deemed ok or not looked at at all when it was still there hours later.
