Hopefully you’re only clicking on ads that interest you. They do not pay you for clicking ads and you don’t see any extra.
Keep in mind we haven’t determined you’re flagged. I just answered some of your questions earlier. That said, I’m not sure how to read the sentence you had here. Hopefully you’re saying primarily keep connected to the country you have set. So if you’re from England, you’re using VPN to say you’re in England. If you’re England but then shifting VPN to be in country you travel to, such as USA, then that could be a conflict that at least can contribute to issues.
Again, depends on what people mean. All we have to do is let the ads appear. No interaction necessary. So constantly clicking on ads and trying to maximize them completely, it might be seen as unusual activity and be flagged too. When I say about maximizing, an example is that a while back it was announced that NTP ads would be limited to one ad every 15 minutes. There have been a lot of people who try to open new tabs almost every 15 minutes on the dot to try to get maximum ads.
Biggest thing of all is to remember Brave is about casual use. It’s not supposed to be just to earn Rewards. You use the browser as you normally would and earn whatever you earn. Usually this is what leads to people not having any issues and actually earning higher than usual amounts. It’s people who try hard to maximize earnings that tend to earn less in the end and might even get flagged. Take it for what it is, but that’s my personal advice on it.
