So every so often I get a message from Google for instance that says “we have detected suspicious activities from your IP address and we need to verify that you are you” so I have to do a captcha or swap servers.
Can I get in trouble for what other uses using the same VPN server are doing?
If you are not hosting the VPN server, the worst case scenario is that the IP of the VPN is banned.
Most people who create botnets and other things use a VPN to bypass google’s rate limiter. So you’re lumped in with them. You won’t get in trouble but some services don’t allow VPN users.
