If anyone recalls the old “Girls Gone Wild” days where they sold videos/dvds via late night info commercials there was a very famous criminal case and civil lawsuit that put them out of business because they filmed underage girls who produced fake identification...while most crimes require intent and the fake ID would generally have made it possible to prove intent, underage sex/pornography is a strict liability crime so if it happens it’s criminal regardless of intent.

Subsequent to those underage cases which began in 2003 additional civil lawsuits were also brought against the company for other issues, but those underage cases were still ongoing.
A different example would be the Hogan/Gawker case which started in 2013. The company faced other lawsuits after, but it was the hogan case that pushed them into bankruptcy because it didn’t end until 2016.
