So, it's been a couple of days. Has your status changed back to human yet? :) If not, have you been in contact with the creator(s) of steemplus?
I imagine it hasn't happened very often, but to be classified as anything but human, regardless of your actions, unless you're actively using some kind of script to do certain activities, should never happen. A bot never signs off or sleeps. It's constantly doing things. It's always there. Humans are not. As efficient as we would like to be, we're just not going to match the efficiency of a well-scripted bot.
I hope it's back to normal, and that if there's a bug in the browser that it is fixed. :)
