1 ) I didn't know that

3 - a, b, c ) I see your team was already working on the solution before I even spotted the possible problem. I wouldn't expect less from you guys ;)
3 - d ) Woudn't it reward massively bloggers that already have good reputation ? If I had a bot following me and voting up after a minute anything I post, I would certainly post lots of low quality blogs every day.
I fear that bloggers that usually make a few hundreds of $ on their post continues to earn the same amounts (or even more) independently of the quality of their content. Only because bots and people expects them to continue earning this much.
