You get 5 chances (the black popup) to vote the way they want you to vote and then you are banned. Banning means you only get 3 posts a day. The banning seems like it is done by a human because it actually takes several minutes to take effect.
It's a bad idea and the introduction has been insanely badly handled. Way to go Globe and Mail.
I guess you could just always vote every article as uncivil. That would work work for a while, then they will put in metrics to see if you are voting too uniformly.
If they are going to say that after a certain number of "UNcivil" votes for an article that everyone after that must vote the same way why are they even continuing to ask people's opinion? Seems very poorly thought out....  maybe they don't see the problem with "It's a democracy and you get to have a vote - but you have to vote the way we want you to vote. But hey not only do you get a vote but you must vote!!"
