Twitter account creation bot (+ auto tweet)

I'm looking for the best bot for account creation on Twitter.
And bonus points if once the bot created the account it can also Tweet.

So the workflow would be: craeate account - tweet - log out ... repeat infinite

I saw TweetAttacks Pro, but I'm not sure it's good (I tried other products from whitehatbox and I wasn't convinced) and I'm not sure if he can post after having created the account
