According to them they share what they get from revenue but the truth is that they always pay 1 cent for every view / like / comment. It's always a cent. This makes it very easy to earn from the site because if you write popular content that gets a lot of attention you can make money without much worries.
Unlike with other sites where you should rejoice when your article gets more views, I think with Bubblews, the case is quite the opposite. I've known really good writers there who got in trouble as soon as their articles go viral. It came to the point that 200-500 views or higher is already considered "massive views" level. Getting a lot of views caused by either organic traffic or through promotion could be a cause for worry. They deal with this problem by asking the member to just delete that particular post getting massive views.
Yes, the posts earn 1 cent per action: 1 cent per view, 1 per comment, and 1 per like. That's what I understood.
In addition, not all who missed payments have violated the TOS. The admin already admitted that they have had payment issues with members without any violations. They're trying to fix that now.
