Here is the relevant text:
Publishers affirm that they are either more than 18 years of age, or possess legal parental or guardian consent, and are fully able and competent to enter into the terms, conditions, obligations, affirmations, representations and warranties set forth in this Agreement.
So, assuming you’re “competent”, there doesn’t seem to be any problem. IANAL, though, and I’d suggest you to read the terms anyway. Not doing so is exactly the same as not reading a contract you sign.
