I have an idea that could work well with twitter, and I want to try it out but since i have never used it I have some questions. I would really appreciate it if someone took their time to answer. 
1. I heard that twitter only uses ip checks on account creation and not on logging in/usage. True or false? If I don't have to switch proxies all the time that would help alot.
2. Any good bots to automate your accounts with following and unfollowing?
3. How harsh are twitter with suspending accounts for mass following generally? Obviously I will try it out myself, but a general starting point would save some time.
Thanks
