I'm surprised someone didn't create a bot that would automatically use the bot to vote on their post with the best bid possible whenever a new round of vote begins. It might already exist but when I last look at bottracker there was no evidence of such bot. It's only a matter of time I think.

I definitely think that the best way for the "good" guy to use the bots is trying to use them more often than the "bad" guy and I see no other way or reasons for people not to attempt this.
