Where Is The Logic Banning New Characters For Existing Accounts on Congested Server?

[Toutatis]

As other have said there is no ban. If you want to create a character on a specific world to play with friends, you may want to start checking early am (like 4-6 am where the majority of the player base of that world is located). Some worlds might still be congested at those hours but it is much better now than it was a month ago.
