If links are truly a problem then I would believe it wouldn't even be necessary to remove them and also it would require more action than simply "blocking" links you think are bad.
Google is more than liking simply blocking any kind of benefit these links pass. So if you remove the link you are still going to be left with the same outcome/same traffic.
Basically I wouldn't waste my time trying to remove links and spend my time building quality links that will benefit my site.
