What are the guidelines when creating a custom username?

Your custom username should be your name. When creating a custom username, it is important to make it easy to remember and easy to spell, so it is easy to find you.

Custom usernames should not be too similar to existing usernames, should not look like spam, and should not be offensive. Don’t impersonate anyone, don’t use offensive words, don’t use usernames like (admin, moderator, or trying to impersonate anyone from our/other companies)
