To add my anecdote on this topic: I was cut off as well. I had a friend who used my wifi with an infected laptop. I had no trouble getting the block removed the next day, but it probably helped that I use Linux and was not the real source of the malware. My friend was unable to clear his laptop, he had to reinstall windows. I thought the action was reasonable, since the laptop of my friend had become a real hazard.
