Overall I suggest that we add another key to `ACCOUNT_TYPES` dictionary, to point to a list of validators. Then this function will just run the validators as defined per field.

Example
`11:{'name': 'Website URL', 'url': '{username}', 'validators': [URLValidator()]},`
`6:{'name': 'Twitter', 'url': 'https://twitter.com/{username}', 'validators': [TwitterValidator()]},`
