It takes time to contact,
and you are willing to open holes across your network for every tom, dick or sally that wants to share files with their pal across town? (or off your network) If people want to use the network they need to take the responsibility and patch their systems. Blocking should really only be considered in very extreme circumstances when your network is being affected by the problem, or if the overall threat is such that a short term network-wide block would help get over the hump.
