What you are doing with the Ecotrain bot is taking an active approach to combat all the negativity surrounding it. Whitelisting seems to be a great way to ensure that the bot doesn't become abused. Personally I love to use it to upvote other's posts. It's a great way for me to help since my account's vote value is so low.
Thank you for being an awesome being it is clear in all your missions that you really do contribute so much positive energy into making, not just steemit, but also the world a better place. Thanks again for everything you do. :-)
