Microsoft has disocvered Leetspeak and the risk it poses to children:
Key points for interpreting leetspeek
• Numbers are often used as letters. The term "leet" could be written as "1337," with "1" replacing the letter L, "3" posing as a backwards letter E, and "7" resembling the letter T. Others include "8" replacing the letter B, "9" used as a G, "0" (zero) in lieu of O, and so on.
• Non-alphabet characters can be used to replace the letters they resemble. For example, "5" or even "$" can replace the letter S. Applying this style, the word "leetspeek" can be written as "133t5p33k" or even "!337$p34k," with "4" replacing the letter A.
• Letters can be substituted for other letters that may sound alike. Using "Z" for a final letter S, and "X" for words ending in the letters C or K is common. For example, leetspeekers might refer to their computer "5x1llz" (skills).
• Rules of grammar are rarely obeyed. Some leetspeekers will capitalize every letter except for vowels (LiKe THiS) and otherwise reject conventional English style and grammar, or drop vowels from words (such as converting very to "vry").
• Mistakes are often left uncorrected. Common typing misspellings (typos) such as "teh" instead of the are left uncorrected or sometimes adopted to replace the correct spelling.
• Non-alphanumeric characters may be combined to form letters. For example, using slashes to create "//" can substitute for the letter M, and two pipes combined with a hyphen to form "|-|" is often used in place of the letter H. Thus, the word ham could be written as "|-|4//."
• The suffix "0rz" is often appended to words for emphasis or to make them plural. For example, "h4xx0rz," "sk1llz0rz," and "pwnz0rz," are plural or emphasized versions (or both) of hacks, skills, and owns."A Parent's Primer to Computer Slang: Understand how your kids communicate online to help protect them" by Microsoft Corporation
And here's a set of kewl words that Microsoft says you should be on the lookout for:
Leet words of concern or indicating possible illegal activity:
• "warez" or "w4r3z": Illegally copied software available for download.
• "h4x": Read as "hacks," or what a malicious computer hacker does.
• "pr0n": An anagram of "porn," possibly indicating the use of pornography.
• "sploitz" (short for exploits): Vulnerabilities in computer software used by hackers.
• "pwn": A typo-deliberate version of own, a slang term often used to express superiority over others that can be used maliciously, depending on the situation. This could also be spelled "0//n3d" or "pwn3d," among other variations. Online video game bullies or "griefers" often use this term."A Parent's Primer to Computer Slang: Understand how your kids communicate online to help protect them" by Microsoft Corporation
Remember, kids, if someone offers you some "pron" just say, "Thanks, Dude!". Or, more properly, "10x d00d!"
