Just came across this story.
In March, a 51-year-old Reddit user named "Black Visions" -- Jerry, in real life -- wrote a post in the "Men's Rights" subreddit called "A lot of trolls tonight." He had been writing frequently about depression and suicide, but when Jerry announced his final post on Reddit and also threatened his own suicide, others decided to egg him on even further. That turned out to the be the last straw: Seattle news soon reported Jerry had jumped eight stories from a hotel room in the Double Tree in Tukwila, Washington.
Reddit announced on Wednesday that the user's sister Sandy...has filed a wrongful death lawsuit against nine Reddit users who egged him on, but Reddit has also been subpoenaed in identifying the information of another three individuals.
Does the woman have a case?
I had trouble deciding which forum to post this, so if mods think it's appropriate elsewhere then by all means move it.
