CSV import added new users into developer role

[Kevin Dalton]

We just imported 61 issues and the CSV had bad user ids.  After we deleted the issues and reimported with the correct ids we found all the bad ids had an account created which was easy to delete and expected but we also discovered all the bad ids were added to the developer role of the project.  Why did this occur?

I believe that when the importer creates new users from the Assignee field, it adds them to the Developers role to try to ensure they have the permissions to work on the issue, but that's just my take on it.
