Not sure what the hardest was for me but Scarlet/Violet have by far been the easiest for me. There was literally no challenge at all.

Genuine question: How can an ISP detect that someone is downloading illegal material if the actual content is encrypted using SSL/TLS? Is it all approximated based on the domains/IPs and the amount of data that is sent? If they can’t tell with a 100% certainty, can it be used as proof when trialed in court?
