Hi! Thanks for making this great plugin.
Like Carlos, I've enabled double opt-in, but I'm still getting a lot of spam from my list sign-up form.
I can tell they're spam because they're coming in with blank values for the First Name and Group fields (and they're also really "spammy" email addresses with zero opens or click-throughs when I email them)
I've got your checkbox enabled on my comment form and that seems to be excluding spam comments (via Akismet), but for my newsletter list signup form (in sidebar widget), I'm getting 5-6 spam emails a day. I guess they're confirming their subscriptions in the double opt-in emails through some kind of Bot or something?
Is there any way to add a honeypot to the form? I would upgrade to the Pro version to get this feature.
Thanks in advance :)
