In the Starcraft 2 community it is called barcoding. Basically, I 1 | l are all accepted characters for a name and I think some do look actually identical on most fonts used in the game. So yeah, one person doing that you call "barcode", 2 persons doing that, you already have deniability. Be more than 10, and that's a crowd.

  • There was a time where call of duty ghosts was exploitable, and people could wipe/delete the accounts of anyone whose username/gamertag they knew. Streamers and pro players had to use barcode usernames to avoid getting their accounts deleted.

  • Google's AlphaStar StarCraft bot did just this under different accounts. Along with some other fingerprinting, many of the accounts and replays were found by the SC2 community.

    • To my knowledge, it played with only one account. It played exactly 50 games with every race. It was outed mainly because of two things: A very high win rate (above 80% IIRC) and the fact that as a zerg it produced units by selecting larvas directly, which no one ever does (someone explains that it uses control groups but they are hidden and dont show up in replays, I dont know how accurate it is)

  • Back when I used to play Ingress, that was really common. The Enlightened in Dallas had a ton of barcode names.

    • The new client makes it much easier to distinguish the characters, but there are still plenty of barcodes in the game.

  • You can reuse names in SCII, so it’s more a convention than anything else. The important bit is to have many accounts with similar names.

  • this goes back at least as far as the original Unreal Tournament, I even saw a player using it in the fairly obscure Shogo: MAD multiplayer community. Never knew why it was done back then, I assumed it was just to be cute, but it did make it troublesome to mention them in ingame chats.

I actually saw a car with a license plate like this last week. Some combination of I's and 1's. White Ford Mustang driving around Santa Clara.

  • In UK number plates I and 1 are the same character, as are O and 0:

    Number plates existed for decades before ASCII was invented. Before computers, people often used mechanical typewriters which didn't have keys for 0 and 1: you typed 0 as O and 1 as l. I threw away one such typewriter recently. It was in good working condition, with its instruction manual. It had been made in a country that no longer exists. You may imagine how sad and nostalgic I felt.

  • I've seen something similar in New Zealand. Probably wouldn't be fooling anyone given the size of the country and how distinctive the car was.

Saw a similar one on the road in front of me with a combination of N's, M's and I think a W ... man it was impossible to get straight while moving.
