I believe you have to be level 2 or higher to be eligable for the rain.
And yes, active in chat. Some people are on it 24/7 from what i've seen
I doubt people would work for a chat bot in order to just claim rains but if they could somehow manage to make that work, that would be something special not because it could earn money but we are talking about a bot that would write down some words you have coded into it and not get caught. What could you write and say that wouldn't attract any suspicion?
Think about it, if all real humans stopped and only bots left we would see totally unrelated words and sentences all post there making absolutely zero sense. That is why I think it is close to impossible not because of coding sense, I don't know coding so I can't speak about that, but it is impossible about the making sense part, not getting caught part, I doubt that anyone would be capable of not getting caught with something like that.
Yeah, we even talked about how people could be making bots about it as well. Rain is cool and all but it is more like lottery, it shouldn't be a reason to be here, but it should be a good side thing to have when you are already here, if you come here just for the rain, you are basically just spending time for something that may never happen to you at all, and that just doesn't make sense at all, but if you are already here, if you are already gambling and if you are spending time chatting with other people at the same time, well then rain or no rain you will be happy but with rain you will be happier.
I have seen huge amount of rains here, you could be seriously happy, yet it shouldn't be the main thing. Also, does casino gives from their own share of profit to this rain? Or does investors get affected by it as well?
