I still don't see why there would be a problem collecting things like the advent calendar. If you do have each account under a different e-mail address, and keep the trading/giving between accounts to a minimum, it should be okay.
Say if two of you you want to exchange two items, use the trading post instead. Treat your accounts how you would treat the accounts of other players, and it should be okay. TNT has stated it in the editorial a few times.

I was wondering whether it is a freezable offense to visit the advent calendar with more than one account? Not sure if i ever heard before whether it was or not and i dont want to get an account frozen. Thanks ~ karmakitten17
Yes, it is. You may NOT visit the Advent Calendar with multiple accounts. Your siblings and other family members may visit on their own accounts as well, but just one account per person please. To make sure you are not confused with your family members, please be sure to have a unique email address from those of your family members to reduce confusion.

And like I said, on the off-chance that something DOES happen, sending in the freeze form and explaining the situation should clear up any misunderstanding. But the seperate email address thing usually does work. Just remember to keep the sending items and NP between accounts only to what is necessary, if you do it too much they might get a bit suspicious.
