"For security reasons and to help ensure the integrity of the game and auction house service, players who purchase the digital version of Diablo 3 may have to wait until payment verification is complete before they can access certain game features," it explained.

"While most payments are approved and restrictions are lifted within a day, in some cases it can take up to 72 hours to complete this process.

"Similar to World of Warcraft, these restrictions were put in place to deter credit card fraud, which in turn helps reduce gold spam and other harmful activities that can have a negative impact on the game experience for everyone."

Here's the official list of restrictions:
- No public game access for unverified digital purchasers
- No auction house access (real-money or gold) for unverified digital purchasers
- Unverified digital purchasers cannot trade items or drop items for other players to receive
- Unverified digital purchasers are not able to chat in any public or game channels
- Unverified digital purchasers cannot attach a custom message to friend requests, but they can send/accept friend requests, and play with their friends
- Global Play is not available for unverified digital purchasers
