If I may conclude - at least for the moment - the discussion here and under the article you linked above, I have the impression that a certain number of users has already noticed the problem of "creating money" by self-voting but they are not happy with the situation and find it morally questionable. The question seems to be now to establish some rules (or system updates) to avoid abuse of the current situation.
Hopefully, the number of users who realize the problem and who are aware of the potential abuse will grow and so the coders are forced to react on the problem.
