I don't know what battle.net is so I was speaking generally. Since pictures don't have security features on them it wouldn't be too difficult to photocopy your own id, change the name/address, print it out and glue it on a plastic card. You now have an Id that looks good enough for photo verification. It's a lot of work but if the steaks are high then it will be done. There's also the case when these pictures get leaked, there's a lot of people who have scans of my id. Or just photoshop the pic after its taken. There's services on the darknet where you can buy these fake Id picture/scans as well.
