How many pre-orders will I need to miss before they close my account?

I've quit toy collecting and I'm the kind of person who needs to burn bridges to move on. I want to close all my accounts, ninin are the only ones who won't close my account, I have a lot of outstanding orders with them I don't want anymore and can't be bothered to sell, I'm worried they will just ban me from pre-ordering stuff not close my account, I have five pre-orders atm. I've missed one and they haven't even sent a threating email yet.

Idc about getting black listed or losing money, and just want to move on with my life.
