`\w+` matches `[a-zA-Z0-9_]`. At some point this URL won't match an existing username, because `User.username` accepts other characters too.

From the `django.contrib.auth.models.py`:
```python
username = models.CharField(_('username'), max_length=30, unique=True,
        help_text=_('Required. 30 characters or fewer. Letters, numbers and '
                    '@/./+/-/_ characters'),
        validators=[
            validators.RegexValidator(re.compile('^[\w.@+-]+$'), _('Enter a valid username.'), 'invalid')
        ])
```
