alias

Another name that people use to disguise themselves. This can be done anywhere, but is usually online because it is hard to identify someone's true name except through their IP address, which isn't foolproof. Variations on the word are aliasing, the present tense verb form, and aliaser, referring to the actual person hiding behind their false name, whose identity will never change (in online situations). Aliasing is frowned upon because people may think that you're a new person, or in small-community games where everybody knows everybody, possibly even cheating. People like to get to know a regular client's personality, and develop a friendship or rivalry with them. Aliasing disrupts this, since you never know if you're talking with friend or foe.
