I’ve been seeing this more and more lately with Mailchimp.
I like an article, decide to subscribe to the author. And then bam! I’m hit with a captcha.
I find this quite insulting. I’m joining your email list so you can sell to me, and you treat me like a spammer? Fine then, I’ll just leave.
And it’s always with Mailchimp. Mailchimp has this idiotic policy where stopping any potential spammers is more important than anything else, even if you are turning away honest people. Far as I can see from their docs, there is no way to turn it off.
I dumped Mailchimp a year ago and haven’t looked back. It’s sad to see other people losing subscribers and not even knowing about it.
