When a new instance is created, the last used name is pre-filled. This poses a potential personal information risk.

In particular, when starting a Public or Friends+ instance, there is a suggestion that specific friend information (e.g., from an Invite instance) or other personal information may be Somehow exposed.

Significant, whether the last used name is auto-filled should at least be an optional setting rather than the default. (Rejected, I would be fine if this feature didn't exist at all.)

Japanese:

Risk of personal information disclosure due to automatically entered instance names

When setting up a new instance, the last name used is automatically entered. This could be a risk of personal information being leaked.

In particular, when setting up a Public or Friends+ instance, there is a possibility that specific friend information or other personal information will be unintentionally disclosed from the Invite instance, etc.

Therefore, I think whether or not the last name used is automatically entered should at least be an optional setting rather than the default. (Personally, I don't mind not having this feature itself.)
