The breach has been confusing some people like they didn't breach nintendo and all that, But are goal wasn't beach nintendo directly but to steal some pii, operational plans, all private chats of employees. This Breach doesn't affect nintendo gaming wise it only affects a small amount of employees that work for nintendo and have used tinypulse. Tinypulse you have till june 16th 2026 to contact us via telegram or email that we have sent you. Nintendo decided to not pay so we are demanding that tinypulse pays or all data will be leaked including private messages on nintendo employees and not all employees are happy we can tell you that. Private messages are about to not become private if tinypulse doesn't reach an agreement with us. This is all we have to say about it no further questions. it's simple if they don't pay there leaked. This is just the file tree of all the data we stole so you can actually see that there are w9 forms with employee id's.
