Recruit a Friend to a diff server than mine?

Can I recruit a friend but have them start on a diff server than the one i am on.?
I don't plan to level a toon with them and with my server being notorious for being very behind on content i would never recommend my server to anyone. I will also never leave it because its home.

and if they can start on a diff server do they still get the 3x exp and do i still get my mount? ( i just want my rocket)
