I do not see any warnings about needing a VPN.
why do you need a VPN?
well when you connect to a torrent swarm your IP is shared with anyone else connected, so if a pirate hunter is connected they gather all IP:s they see, send an e-mail to your ISP and ask who had IP X at time Y on day Z.
popcorn time fundamentally works on torrent technology and as such this weakness is present.
a VPN (theoretically) denies the pirate hunter the ability to request who was using an IP as they (theoretically) don’t log that information.
so yes, a VPN is still required.
if you want a secure connection that a third party cannot spy on, I can recommend visiting /r/usenet, which does come with the drawback of being a paid alternative.
browser version?
can you share tue url please?
Do I need a VPN for other services such as 123Movies or 9anime?
theoretically no. a connection between you and a website is private.
however there is no guarantee that website isn’t selling data.
some use webtorrent so yes
