You publish something on the internet. That something is reprinted in its entirety within an essay without your permission. It is reprinted on a hate site. It is being used as an example of the imagined evils of society. You are worried about the type of person who would see this and try to track you down. You are also worried about calling further attention to yourself since while reprinting the entire work is against the law, printing excerpts is completely legal, and they could easily add parenthetical remarks such as (due to threats of legal action rest of work has been removed from essay) which would increase my fears from website visitors.
(I linked to this reprint last week. That link has been removed.)
