I've upvoted the post of Olin because I think this is obviously better than the current situation. Nevertheless, this does not completely solve the problem of trolls using multiple accounts. I think a minimum of 100 pts to get the rights to downvote would solve it completely, in addition to the suggestion of Olin (which is a good thing by itself anyway). 

**Answer to Kranulis:** it's OK to downvote an answer because you think the answer is rude or condescending etc. Just say it! Also, not everyone is a native English speaker, or speaks the same English, and different persons think something is condescending while other persons think it is not. The best way would be to indicate that in a comment, and give the possibility to update the answer. But if you prefer donwvoting for that, that would not be a big problem, again.

The problem, dear Kranulis, is when a user creates several accounts, and use them to downvote and impose his views. That's disgusting. For example, I know most of the avatars of a certain troll in this site; that would be a big surprise for him if I come to reveal them all.
