consider additional security for forms on www.ietf.org

[ghwood]

Web forms on www.ietf.org currently do not have any mitigation against automated submissions.

Some amount of "spam form" is currently received.

Current published form pages (and submission emails) are:

https://www.ietf.org/forms/wg-webex-account-request/ ([email protected])

https://www.ietf.org/contact/contact-form/ ([email protected])

https://www.ietf.org/forms/keyword-suggestions/ ([email protected])

Additional information about the volume of spam is needed to understand the urgency of the current situation, but some systemic approach to mitigating form spam should be considered.
