Where leetspeak came from
Leet, from “elite”, grew out of bulletin board systems and early online gaming in the 1980s and 1990s. Swapping letters for numbers and symbols marked you as an insider, and it also slipped words past simple filters that only looked for exact spellings. Today it’s mostly used for fun, in gamer tags and jokes.
The common substitutions
| Letter | Basic | Advanced |
|---|---|---|
| A | 4 | 4 |
| E | 3 | 3 |
| H | H | |-| |
| I | 1 | ! |
| L | L | 1 |
| O | 0 | 0 |
| S | 5 | 5 |
