skip user iter if already banned

[AndrewPaglusch]

This update addresses a flaw where the script could re-ban an already banned user. This occurred because the script was assessing a user's stream history and concurrent streams for potential banning, even after identifying the user as already banned.

This update resolves the issue by adding a continue statement to skip the remaining loop iteration once a user is found to be already banned. This prevents the script from reassessing and reapplying the ban on the same user within the same iteration.

Redacted logs showing this happening:
