Yeah, Dezeral is correct. I'm not sure from where that Turbien employee quote was pulled but it is indeed inaccurate. You can absolutely have multiple subscriptions of LotRO on the same account.

This statement can actually be found in the F2P FAQ sticky on the forums.

Don't be concerned about multi-boxing. It is prevalent in most every MMO out there. Turbine's stance is that there is nothing wrong with it--they just don't support it. So, don't file bugs about multi-boxing issues as you will only get a canned response that you will not be helped.

Continue to ask questions here or on the the LotRO forums--just be prepared for some heated, and often idiotic, posts on an multi-boxing thread you might start.

Happy hunting!
