I think it's to do with things like people using 'troll' accounts on facebook to write abusive things on say a page dedicated to someone who died, there's a big difference between that and many other kinds of 'trolling', I wouldn't even call that trolling, it's just tasteless and brainless abuse, infact it insults the meaning of trolling and I am glad people can't keep hiding behind fake names and accounts to torment people about their dead family members.
