We all vote at times tactically its something that can be hard to avoid, and with bots being involved it just ads another level to people not caring about actual content and really we should all vote for what we enjoy and not vote for posts we recognize as poorly done just for the rewards.
It is one of those areas that if we were to all tactically vote on occasion it would likely not be an issue but because people use bots and almost exclusively vote tactically it becomes the issue it is today.
