Hi @gastan
no, unfortunately we do not support any contact form plugins at the moment. You see this on our FAQ:
Antispam Bee works best with default WordPress comments. It does not help to protect form plugins and does not prevent spam registrations. Hopefully we can provide better hooks for third party plugins to use Antispam Bee to fill this gap in the forthcoming new major version.
FAQ
As pointed out in the FAQ we are working on a new version and hopefully we have a public beta soon, that will either support this directly or has the ability for third parties to close this gap and add this to ASB.
Thanks for your patience!
All the best
Torsten
