So I have been loyal to hotels.com for a while, I like the way their rewards program works, you get a 10% return, it's stright forward and simple.

I was wondering, is it allowed according to their rules to book hotel rooms for others while earning the credit for it assuming I will not be staying with them? I know it's possible and have done so in the past with friends and family but now that I already have over 12 nights to use (around 128 nights stayed with the site) am a little worried doing so and risking an account closure.
