I watched the video 4 you.
Like every place where money is involved, steem also attracts the abusers, the begging people and the spammers. I don't think we can do anything against these people. But at least you can find open minded good people here.

I barely user steem now, but as I know the main problem is we need more manual curators to reward quality content. I used to be curate manually, but it is really hard and you don't get the reward for it. We need a system to reward manual curators against bots and autovoters.
