Definitely watching the evolution of bots, I'm seeing them comment on posts then bots downvote them.

BTW, when I upvoted your post I saw your rewards got from $5,434.79 down to 5,306.86! Sorry for whatever made that happen, yikes!!!

My voting usually makes rewards go up, sometimes down (which has been puzzling me), this was the most dramatic change I've seen.

Any ideas on why this happens would be most enlightening, as I don't want to be put off upvoting articles I find worthy when my vote is decreasing the rewards (this was my first vote of the day). Otherwise I'll just let the bots roam free while us humans remain bewildered by it all :)
