The difference between soul and souler is that one is a noun and the other refers to a person.

In fact, there is only the word "soul" in the English word, and there is no word "souler". Because the user's personal information in this software does not have a nickname, only a personal signature, many users have already used the personal signature as a nickname. Everyone who starts chatting is a black box. The name of this black box is "souler", just like people who write code like to call themselves coders.

Judging from the product logic, when users are chatting, they are immersed in the chat itself, rather than paying too much attention to the user’s personal information and deciding whether to chat or not. This is a kind of violation of the current normal social thinking. The way to go.
