Traffic cameras hate this one weird trick

Can't say too much but god I hate this so much. Used to work a call center and someone had a username that was all 1,l,I s and there was no way to easily identify between those 3 characters. For someone to verify who they were they needed to tell us their username and some other info. So I had to waste nearly 30 fucking minutes dealing with this stupid shit before we could proceed forward and we couldn't just DC the person.
