Alice is 30 and lives in the EU. When she was underage (say 14) she willfully took photos and videos of herself masturbating and/or performing explicit sexual acts. She still has those photos on her computer.
Situation A: She is charged with an unrelated crime (e.g. fraud) and her computer is searched by the police, who find the files.
Situation B: She now uploads those files to an American website, and sells them to get money from pedophiles willing to see them.
Situation C: She willfully uploaded those pictures to the Internet when she was 16, without asking money for them. The pictures are now public, uploaded to servers in many different countries, and she is OK with it.
In what cases and to what extent would she be liable for child pornography related offences?
