Actually I think the new rules are good. 75 characters is not burdensome, and bitmixer is paying, so they can insist on higher quality posts.
I am new to the campaign (two payments), and it is hard for me to see how I will ever post 50 times in one week. (Of course, being somewhat of a beginner and not a programmer would make it harder for me to reach 50 "worthwhile" posts)
"He who pays the piper calls the tune."
EDIT:
bitmixer's bot is really something! Automating tasks is one route to making more money....
