One of my accounts got suspended couple of days ago and here is an email from Twitter: "Hi, The following behaviors are violations of the Twitter Rules: ? Creating serial and/or multiple accounts with overlapping use cases ? Cross-posting Tweets or links across accounts ? Aggressive following, particularly through automated means As such, these accounts will remain suspended. " I am running 60+ accounts all with the same approach and only one got "will remain suspended" Account is almost 2 years old with good quality tweets, many retweets and real, natural followers - 2.5k. Tweets are all unique on each accounts (mix of quotes and Amazon links) so I don't know how it could be considered cross-posting. Aggressive following is completely out of questions - account only follows back. Serial and/or multiple accounts - account has private proxy. Tweets are posted with Tweet Adder 4, followback/unfollow with Tweet Demon. So my questions are: - How Twitter can detect multiple accounts if you use private proxies and out of 67 only one account is detected? - What could be the cause of such a suspension? - How can I prevent same thing happening to other accounts? - Should I email Twitter and say what to unsuspend account or just forget it? Any advice will be appreciated.
