I've attempted to ignore much of what has gone on. But having been tagged in multiple posts was quite annoying. It was also attacking people who have helped me a great deal here at SteemIt.
The only reason I could see using a bot for auto flagging is if the person seems to be abusing the system and or attacking people on a constant basis (as noted here) with no sign of reform (I've seen no effort). Some people make mistakes and fix them and other make no effort to fix the problem. If a person is making no effort to fix their mistake then I see the reason people would use a bot to auto flag them.
