While I am not a big fan of voting bots, I do not think that they are going to go away. There is too much money in the top being made on them and I do not think that enough people will stop using them for it to make a dent in their profits. I do not view the trending page for the very reason that it is not a true representation of what should be trending content. It is just sad that so many people think that the only way to make it here is to use voting bots and make rich people even richer while gambling their money away. I am also not sure how using capchas would really slow anything down with the bots. The people that are determined to make money with that system will find a way to work around it. It would be nice though to see a real proof of brain here on the platform, because then Steem Cleaners wouldn't be so busy.
