Are you contacting webmasters to remove them or are you using the disavow tool? What else are you doing to control your backlinks? I would also like to know if you don't do anything and don't have problems with your backlinks. I'm trying to find out how important it is to manage my backlinks. Some companies contacted me to remove an un-natural link from the forum. At the moment I don't do anything to control them. Should I start doing something?
