Share login with paid account

Hi, 

I am considering paying for access. However, am I allowed to share account with my partner, and be logged in simultaneously from two different IP addresses? 

She stay home and will log in from Poland. While I work world wide and log in from various locations, often using a VPN. 

My experience is that this may cause a blocked account suchlike Netflix, amazon and even google. I would like to know if this would be the case also with seeking Alpha. 

While using VSAT internet access, the IP address often changes several times during short time. Often VSAT is my only option for internet access. 

I hope you are able to assist.

Best Regards,

Daniel Hjelm
