Ask any Enom ETP account owner (a top level account that makes a $3000+ deposit, at least that is how much it was back when domains were $6.95).
Your enom account can be manipulated by your ETP owner, unless you are directly under enom (in which case you might be paying $40 for a domain, hence people use ETP parents).
I have access to this feature. You can try the following account on eNom, I don't believe there's any indication I have management access. There's a login link for me to "take control".
Someone could take your domain without any notice at all.
The moment someone gives you a domain in enom you better push it out to another top level enom account (and then maybe even transfer out of enom).
Especially if the account is "created for you".
