okay so I keep seeing people throw around the importance of vpn kill switches like they're some magic safety net. fact is most reviews ignore real world testing and just assume they work. did a little experiment on a few of the popular services, wanted to see what actually happens when the vpn drops unexpectedly. turns out a lot of them either disconnect slowly or worse, let data leak for a couple seconds before cutting off. that seconds can be enough to ruin privacy, especially if you're torrenting or doing sensitive stuff. honestly it's tired to see advice that says just turn it on and forget it. no one checks if the kill switch actually does its job under real stress. stop coping with 'it should work' and do your own tests. no vpn is perfect but some are definitely worse than others at protecting your privacy when it counts
