>>1171920Fucking wrong, and your teacher is an idiot. Except the VPN part. Never torrent without AT LEAST a VPN, and even then you're not 100% protected.
>>1171958It won't work, especially in court. The burden of proof falls on you, the ISP subscriber, to prove that your IP wasn't downloading what the plaintiff can already prove you were downloading. Remember, they already have evidence against you, and reliable evidence at that in the form of logs from your ISP. Gave out your WiFi password to a ton of people? Too fucking bad, the liability still falls on the ISP subscriber, and you'll be told to be more careful with your WiFi info in the future.
tl;dr you're fucked if someone decides to pursue legal action against you.
