Indeed, I do believe there's an important place for Hivewatchers on the blockchain! They absolutely catch bad actors, and I must acknowledge how difficult of a job it is to deal with them on a daily basis. I've had such experiences myself, albeit in a different capacity.
I also acknowledge that there's human error that will occur in such a process, but it's their methods, from what I've managed to see, that tend to lose me more than anything else. I know a lot of people would have preferred a group that would handle situations in a more humane manner. It's not an easy problem nor solution by any means.
