[@alucian] That is the point.
But be warned, we ban out of the project the coin farmers. :-)

And whom would you call a coin farmer? Bot comments, spam comments or something more?

[@alucian] Yes, a coin farmer would just get the money alone. A Commenter get a reward for his good comment. We use a Blacklist and Bots with our manual checking to sort the "bad" ones out.
