CAPTCHA for signing up to stop being hammered with fake accounts

Hi all!

I know I added this as a request in another discussion but thought I'd ask again if it is going to be possible to have CAPTCHA added to logins. SMS confirmations? Anything to make it harder for bots to keep signing up fake users.

I'm currently being hammered by fake sign up's. Accounts are being set up at a terrifying rate of knots. As soon as I manually delete them, back come 20 more.

I've tried to stem the flow by implementing the confirmable module in devise. Thinking that I could set up a task to delete all the unconfirmed accounts every day but this is causing my email quota with MailGun to decrease at an equally frightening rate of knots.

Am I the only person struggling with this? Is there another way to be able to stem the flow of bad signups?

In an ideal world the database would only create the account on the confirmation, but I don't think this is possible.

Any help would be great @ Chris Oliver . 

Hi Darren, I've been having this issue with forms and signups in a few rails projects. 

I just did the following where it was an issue:

It was surprisingly easy and no issues since!
