I think the best way is to share your mobile app's access token with server, this is legal and works unless

the utilization of the access tokens is based on the same agreement the user gave you

That's an official answer from thread https://dev.twitter.com/discussions/4314. Another great citation from there:

Access tokens represent the relationship between a user account and application -- the IP address or host of the machine involved isn't relevant.
