No one knows, but they were most likely from before the maintenance that removed the Spring Event. My best guess is because of that some players still had access to the event maps although they had already been removed, allowing them to continue grinding ships and stuff. I vaguely remember something similar happening during the Fall Event.

In any case, using the API link method doesn't really bear a huge risk of getting banned. Even a lot of Japanese players use that method, after all. Just make sure to update it whenever you can.
