It's news to me that some of the large stakeholders are purposely voting for inactive witnesses to keep other witnesses from moving up. People are free to do what they want with their stake, but only within what the system will allow. (You can't vote for 31 witnesses - so there are limits - as another limit I'd really like to see inactive witnesses purged from the rosters after - I think I've heard proposed - 90 days?) Thanks for taking the time to share this information. I learned a few things today :)
It was news to me too, but I trust @enginewitty to be honest, and he's my source for that bit of info.
