There seem to be two errors:

autoCreateUser failed for <redacted>:
Warning: Username entered already in use.
Please choose a different name.

This is probably a warning, not an error; we should be less strict in the status handling.

* Start of block: [redacted]
* Expiration of block: [redacted]
*Intended blockee: [redacted]

Your current IP address is [redacted]. Block ID [redacted].
Please include all above details in any queries you make.

If you believe you were blocked by mistake, you can find additional information and instructions in the [[m:Special:MyLanguage/Stewards/Wizard|Stewards Block Wizard]].

We probably want to respect blocks, but then the script shouldn't alert on them.

Filed separate tasks:
T432612: backfilLocalAccounts.php should ignore warnings
T432613: backfilLocalAccounts.php should not send alerts when the account is blocked

I don't remember how long the script tries to retry the same user, so maybe this task will have to be kept open for a while, but let's try to close and see.
