If you haven't noticed, your IP address can easily be given out on Teamspeak the moment you join. If you don't have a VPN, you are at risk of many dangers on the system. Someone who knows their stuff can easily find out about someone who doesn't have a VPN, and thus risking threats, blackmail or other dangers. Discord is the better solution of course, there is no other reason not to use Discord for help purposes to avoid the use of Teamspeak. That's the simple explanation behind the vulnerability of being on Teamspeak.
