I prefer (thus far anyway) to run my forum showing usernames vs. real names, and I’ve made the real name field optional. But some of my Google OAuth2 (“Sign in with Google”) users have gotten what are apparently default usernames of “User1”, “User2”, etc. I really don’t like having these generic d…
