I have just starting experimenting with bots and read about minnowbooster and really liked their idea. Used twice and had no issue. Third time I used it I for no reason got blacklisted. Got on their discord and one of the mods told me that they had problem with a new update that put people on blacklist that had done nothing wrong. They say that they are working on it and that I should be unbanned in a week.
Have been using smartsteem meanwhile and it works flawless 😊
