I know it's a lot of work for sure. I think I personally spend about 5+ hours daily on hive between writing, commenting, voting comments, replying to comments and curating. So yes lots of time involved with what you said in this post but also that's quality and encourages others to up their game and do and be better as well instead of trying to game the system. While it wont stop all abuse nothing ever will it's a step in the right direction to minimize it and show others who hive should be used and treated.
