I just bought Tweet-adder after using both Hummingbird 1 and 2 and Bird Feeder. My main account has almost 18,000 followers with me following about the same number. I know that Twitter will suspend accounts for excessive following/unfollowing, so I want to be careful. But having said that, what are the daily limits I can follow and unfollow with Tweetadder while remaining under the radar enough to avoid account suspension? Obviously I want to build up as large a following as quickly as possible, but I'd rather err on the side of caution. With Birdfeeder I was unfollowing and following about 900-1000 per day, but only unfollowing those who weren't following back after being followed for more than 5 days. But I'm thinking maybe I was pushing the envelope too much with those numbers and was just lucky to not get suspended?
