Problem about name and surname information after import


I’ve imported my forum Mybb to Discourse. Before the “@” mark on users email addresses automaticly fill the name and surname information. And these informations can be seem on the users profile page. This is a little problem for privacy. Because user’s email addresses predictably by other users. How can i delete this in a mass?

You will need to delete all the users, there’s no other way. Name mentioning is built in, and if someone picks a username that exactly matches their email, then… that’s what they did.
