I never want to NOT say thank you. I tried it out and it seemed to work until you enter the wrong captcha. None of the accounts I thought were made can be found on twitter, but that may be due to the errors caused by captcha prob. Will not continue if you enter one wrong, making you start all over. I swear I put them in right, tried 3 times. I was making accounts at this very moment, so thought I would try it out. It would be perfect for what I am working on right now.
(update mid post: b4 I said more gave it another try, all captchas entered come back incorrect)
If you need to generate emails, just use a random password creator and input with @G**** right after it. I have never had one be taken yet, and Twtr doesn't care if it is valid. I do this to set up 100 accounts at a time. It is still manual, but i find it helps to reset my IP every 20 accounts or so anyway, just so I never have to look at that annoying "not right now, we're working on it" message. Thanks for the share.
If you can get the captcha to work right (if you can replicate it) and get handling errors under control (I got some each time), It would be the perfect tool for what I am doing. PM me and I would be more than willing to send test info, or to see if I am doing something wrong.
