Yes, I do not have any problem with it whatsoever. There are probably plenty of books that also cause some percentage of people to develop suicidal thoughts, but I do not want to start banning those books.
This is the kicker I think. Facebook scales 'keeping up with the Jones' up and make it easier. But that's been a common trope since (google search... 1920ish). What Facebook's doing isn't new; it's simply Easier.
When you say, '1% develop suicidal thoughts' - Is that causation or correlation? Maybe I'm missing something; but this seems somewhat like 'biggest target' to me as the world had shrunk.
