I agree, they can serve a valuable purpose. It's hard to make sure you use all of your voting power consistently, and if it doesn't get used, it's wasted. I would hope that all users would do it responsibly, with content they do engage with, however. The purpose of the vote is to encourage quality content the voter believes builds the platform. For those that do it a lot, or site unseen, I'd challenge them to take the time to really support those content creators. If you're going to autovote someone, surely, that's valuable enough content to deserve your time and comments as well. I have a few myself. But, they also stop by and comment on my posts from time to time.
