While I can't talk openly, or specifically, about how the API was designed and implemented, I can say that users who are seeing the activation every time they start should contact firstname.lastname@example.org so that we can assist them. That certainly is not the expected functionality.
I play DC myself, so for my own selfish reasons the activation would not have been designed or implemented in that way. =)
Interesting, I see them getting quite a few E-Mails, and soon.
