What to look in a VPN if i need it for tormenting? Either look for its anonymity and privacy or i should look for unblocking?

hey emma. you can read up more on torrents and torrent vpns here. but i'll summarize it anyways... the key in torrents is that they can get you dmca and other sorts of notices, even in cases when your downloads are totally legit, like linux isos. that's why just changing the ip with a proxy is usually not enough and you'll need a vpn that can encrypt what you send and receive.
