I assume you are referring to the account creators' graph. I really can't make any edits because I'm not using the "term" steemmonsters but the name of the account that was actually used to create new accounts. As soon as steemmonsters runs out of account creation tickets and the Splinterlands team uses another account to create new ones, this "problem" will automatically be resolved.
Aha, obvious of course. They still use the steemmonsters account a lot in the back, so makes sense!
