I've been developing my own twitter bot.. It works perfectly fine, logs in, follows, unfollows, sends out tweets, etc. It behaves like a normal person. However, too many accounts are getting suspended. I'm currently running it with 150 or so accounts, and I'm losing 3-4 accounts every day to suspension. I only follow about 90 people a day on each account, and I wait about 1-2 seconds between follows. What am I doing wrong?
