Rule we use to block phone numbers

• We use the following regex to block phone numbers in usernames: https://regexr.com/3c53v.
• More generally, this rule blocks any username that is entirely composed of numbers.

End user experience

• If this setting is enabled, end users will see an error message explicitly mentioning that it looks like they’re trying to use a phone number in their name and asking them to try again.

• This is a customisable phrase you can change in Control (Module: Forum; Key: validation.username.is.phone.number).
