HUGE URGENT PROBLEM: repeated nicknames
When users register, I only collect their emails and names. As a result, the nicknames that show on the forum are their emails. To prevent this, I want to implement the nickname system. But there is a problem in the BBPress.
I experimented by creating a new user and changing his nickname to other people’s nicknames. That is, nicknames should be unique, but it seems that people can just change their usernames to whatever they want, including the nicknames of other people. There is no system that checks for uniqueness of nicknames.
How am I supposed to fix this problem?
