@jonathanbardo Also, the string concatenation here is bugging me. What do you think about something like this?

```php
sprintf(
	__( "ID: %d\nUser: %s\nEmail: %s\nRole: %s", 'stream' ),
	$user->ID, // xss ok
	$user->user_login, // xss ok
	$user->user_email, // xss ok
	implode( ', ', $user->roles ), // xss ok
	PHP_EOL
)
```
