@Mordi But anyway all you need is a bunch of humans to register multiple accounts (manually), then you wire the bot to the already-registered accounts and the problem is still there. It's exactly what propaganda machine do on platforms like Facebook and Twitter.
@Elessar Yeah, it happens. But there would be more bots. Also, I don't think bots are banned on twitter. They have an API designed for all kinds of bot craziness.
