victim of incest
[my adversative decurved garbo]
Ur best bet is to find all their close family members [aunt, uncles, cousins, mother, father, grandparents, even close friends] and either mail them a letter containing all of the wonderful things you saw on their computer OR contact them directly somehow and tell them some shit about internet and porn addiction and set up an impromptu intervention on the people with the computer and when it's all done and over with demand upwards of 7k because you are a licensed interventionist and porn addiction specialist and if they refuse send them some real official looking mail and claim lawyers are going to get involved unless the issue is resolved. At this point offer them a 3k discount because ur such a nice guy and collect ur 4k from them.
If you need any credentials I'd gladly be a reference and the school of NIS is a world recognized place of study with a diverse classroom catalog and your writing your thesis now on sociology and the connection between internet, sex/porn, and addiction with the subject family being one of your top case studies.
