You will notice most spam bots are already getting hidden.

YES! I have noticed it, and I for one am very grateful to all involved in making this happen. :)

people need to watch what they are upvoting. Perhaps look at an accounts history of posting, before you decide.

^^^^^ THIS ^^^^^

Voting alone is not a path to Steem riches. Curation rewards (compared to posting rewards) are pretty small for just about everyone (unless you're a really early adopter or you've dropped some serious bitcoin into this already). Think before you vote. This one action can make such a difference. Unfortunately, IMO, many people are trained by Facebook and Twitter to like anything and everything because it doesn't really mean anything. Even after Dan specifically asked people to stop upvoting introduceyourself posts, people still do. Problems of this variety (stupid people) aren't going to go away with better algorithms (the world is always creating better idiots for any idiot-proof system).

All that said, I'm very optimistic. Things are actually moving really quickly here. What may seem like an eternity in the world of crypto is actually a quick pace for almost any other company. I'm confident the community and those with the most invested in the system will continue working hard to protect their own value.

Thanks for all you do, @anyx! I'm proud to give you my witness vote.
