Thanks for sharing! I'm going to disagree with pretty much everything, so please stop reading here if you're not interested.
I'm not one to stop because of disagreement. You're in good faith and that's all that matters imo
Revenge porn damages someone's reputation, at the very least, which is a large part of why it's illegal.
Someone keeping those images for private use doesn't cause harm, therefore it shouldn't be illegal.
I believe consent is a larger factor. The person who made it consented to have their photos/videos seen by that person but did not consent to them sharing it.
That's why it's not illegal to call someone a slut (even though that also damages reputation)
Someone doing something creepy for their own use should never be illegal.
What if the recording was made without the person's consent. Say someone records their one night stand without the other person's knowledge but they don't share it with anyone. Should that be illegal?
