If the author was underage for all data, all data is deleted. If an author is of age for content, but underage for part, the underage content is deleted. This ONLY applies to what we call OLD minors, meaning pre this staff, that were overlooked. The ones that signed up afterwards, no matter WHEN we catch you, you're deleted.
As the site is clearly marked and labeled for being restricted in age, to users aged 18 and older, there should be no question as to why this has to be done.
You have a problem with my protecting the site in this fashion, that's exactly what it is. YOUR problem.
