Vest (network word)

In order to make people who know you can't guess, another name registered besides the common user name is called wearing a vest. The general forum explicitly prohibits the use of vests to make trouble. Privileged classes such as administrators can find your IP and seal it, but if you are a dynamic IP or use a proxy, it is difficult to seal it.

When a real person registers more than two (including two) IDs in the same forum to use at the same time, the commonly used or well-known ID is generally called the main ID, and the other IDs are called vest ID, which is called vest for short. "Double body" is one of its extended meanings.

On the internet and forums, vest generally refers to the different ID of the same person.

Based on the virtual nature of the network and the multifaceted nature of people, vest is a common and inevitable phenomenon in the network virtual society. The existence of vest makes the network closer to human nature and more attractive than the real society.
