The FFXI-3322 is a client-side error that you can receive at signup. This is caused by a character name violation. Unfortunately, the naming rules are handled by the local client, not by the servers and we do not have any control over this.

A POL-0001 is caused by a core DSP bug (that’s existed since 2014) that pops up when you have more than 5 characters on a single account.
