Thanks for your effort joseph. I'm not sure either who should look into that, but considering the witnesses might not have the time to do then there are not many options left. And then again it comes back to trust and is a lot of work, compared to the time someone needs, to set up a new bot.
It seems most of them are basically trolling or just don't understand anything about what they are doing. They don't even getting any rewards from what I've seen, but they destroy the visibility of almost every post and showing false info with their nonsense votes on every thread.
Yeah hard to find a border, from what point is a bot disturbing or not. Surely depends on the personal point of view. But anyways, there's no way to get rid of all bots, so there has to be found a solution of some kind.
