You need to develop a better system to differentiate who's robots who's humans. I'm really tired for the past week I got 3 accounts suspended without warning nor explanations. Do you think I instantly know where I did wrong in using it after that? I thought I sent too many tweets, but no, after I made a new one and decided to stop excessive tweeting my account still got suspended. Do you think people really know why they got suspended? 🙂
