There are other threads that are similar to this and it's interesting how many people seem to be okay with it. They usually say something along the lines of the accused character not harming anyone and it's nothing to concern yourself with. As others have mentioned, there's a decent amount of players that use third-party tools to their unfair advantage and I would imagine that at some point, perhaps once there's a healthier player population, that the STF will take further action. For now, I'd keep reporting characters and let SE do the rest.
