Lets start!!! This is what i found!! First at all, you need to create your accounts respecting the limits, acting like a human. If you don't know how, buy verified accounts and ask them to put random informations and random photos. Or do it yourself, if you know how to do, respecting the limitations.
IF YOU ARE DOING ALL OF THIS, AND YOUR ACCOUNTS CONTINUOUS BEEN BANNED, I think that i found the Solution. Cause its working for me with BRAND NEW non-verified accounts. Imagine using verified accounts. I'm not using my verified accounts, cause i don't wanna loose them at these tests.
My tests using Brand New non-verified twitter accounts:
You need to use 5 accounts per IP, i already tested it in 2013 and the actual limitation per IP is 5 accounts to run SAFE. In 2011 the limitation was 9 accounts per IP, but in middle of 2012 everything changed. If you wanna send MENTIONS you need to send maximum 4 MENTIONS per hour, just put time interval between 15 to 21 minutes.
But there is a problem, you need to force accounts to LOG IN and LOG OUT, this will bypass the twitter limitation. I lost almost 500 brand new non-verified accounts to find this LIMITATION.
I don't know why, but when you force an account to login again, they will bypass the SPAM HAMMER. Don't ask me why, cause i don't know, but it's working.
How to do this? Example: If you have 2.500 accounts, you use 5 accounts per IP, so you will need 500 PRIVATE PROXYS. So, next step is to select the software to "RUN 2.500 TASKS", then the accounts will run sending maximum 4 MENTIONS per hour, then you set to "PAUSE AND MOVE TO NEXT TASK AFTER" 14 to 21 tweets, so your accounts will be forced to LOG IN again in a interval of 3h30min to 4 hours.
You will need to buy captcha, but they will be used eventually if you follow this steps.
THIS IS A SHORT EXPLANATION! If you wanna to know other things, contact me on facebook, and let's figure out how to do.
Sorry my bad english again, i'm not using google translator. Share your results or methods to bypass twitter ban hammer.
