This is kind of an ineffective campaign. If a person leaves the fandom, then they don't care anymore. Hussie could kill ten characters in one swoop, and the one who left will not care. The people still in the fandom will get angry and try to find said person and most likely post many hateful comments and such. Several options for the harassed will include leaving/deactivating their account, ignoring the comments, or filing a report. I could go on and on about how it would make the fandom itself look bad, but why bother?
