1. How many accounts can be registered per mobile device? Most people are saying 5 accounts, but I have seen someone saying 10 accounts, which it is? 2. If you cross the total account limit will there just be "Too many accounts created on this device" error or can existing accounts get banned? If there is simply the error then I can try out myself where the limit comes, but I don't want to risk my existing accounts just to see if I can still make new ones. 3. How about deleting some existing account using Instagram "I'd like to delete my account" option, would that reduce the total number of accounts registered on the device and allow to create new account? Anyone tried this? I'm looking just to create 1-2 new accounts and would like to use the same device to keep it easier to update all accounts. At the moment I have 4 or 5 accounts created with same device.
