How do you know the bots are losing ground?

That could be partly concluded if @penguinpablo makes another analysis where he posts the top30 accounts that produce the most comments. Or did you did another way?

I am basing this in the fact that the % upvotes is droping. Even below 1. It was a month ago almost 1.6 to 1.7%!
Also less and less SBD is printed, which was mostly used to pay the bots!

That sounds logical and should be true!
