Hi,
I’m also seeing this same issue on my site – it keeps filling up with fake subscribers. I have double opt-in enabled, but still when fake subscribers sign up, I get undelivered notifications (because the email addresses don’t exist) filling up my inbox.
Please consider allowing some sort of captcha as part of the free plugin – I love the plugin but it’s currently unusable with the amount of spam I get. My site costs around $50 a year to run, so I can’t afford to spend $130 dollars a year to upgrade to pro.
Thanks for all your work to build this plugin – it’s great, except for this issue!
