I also have the time issue to deal with, this is why I don't want to follow dead links too often. There are many pressures on my time and attention (as with many people) and having people try to steal more of it with low quality doesn't make me feel like pressing the follow button.
I don't want to bury all of their content (even if I could) because there may be others sat find that same content awesome and love the proactive approach.
