Technically, if you install and enable a VPN program, Linked Helper will work as intended provided that your VPN provider does not restrict access to the LinkedIn web site and / or other web sites that are required by Linked Helper, such as Linked Helper server.
However, you should know that:
- LinkedIn does not endorse when you manage someone else's LinkedIn account;
- VPN program changes the IP address for the whole PC;
So in case you are managing someone else's LinkedIn account (or multiple LinkedIn accounts), we recommend you using a proxy instead so that every account is being accessed from a unique IP address.
