If I will use a reseller plan and the reseller company is okay with me using their TOS & AUP, is there a problem with that?

Nope, no problem at all, as long as you have their permission, its all fine and dandy.

Yes, most upline providers have no problem allowing you to use thier AUP/TOS.

As long as the provider agrees, there's no problem at all. Just make sure you always have permission when using content that is not original to you.

Thanks for the replies everyone.
