There’s no safe manner. I and many other can just make a tiny piece of software that tries to constantly register the username until they get. I could do it for Balthazar since it’s currently sitting at 600a lol. And given how servers are handling the thing, all you need is to have the account creating the name on char select and just an auto clicker on the create button(so no code involved) at the end of the screen would work. Then you just let it run for days or whenever they will do the transaction. Given some people run bots 24/7 I don’t see why they would not just do this since it’s already estimated by the bids.
Ps: I hope whoever wasted their time to log in on release, just to reserve names to sell, not to sell any.
