Additional Spam Protection

I have been using HTML Forms for quite a while now and I’m really happy with it, and for a long time I have also been using WPBruiser since it has a free integration with your plugin. However, WPBruiser has not been updated in 10 months and there are no responses to requests on their WP support forum. Spam is starting to be a problem again and it kind of sucks that there doesn’t seem to be a better solution than waiting to see if WPBruiser will ever be updated again. Are there other integrations available? At least it would be nice to be able to add a CAPTCHA for when all else fails. Is it possible to do so?

Thanks!
