That doesn't matter. A credit system is like an hourly changing flat fee. it doesn't make sense. You might set it at $10 a month, that's it for you. But where is that number coming from. What if you watch a "Just released" movie that costs $10 credits on the first day of the month. No internet for you for the rest of the month? You used to read 10 articles every month, but now $10 you can only read 2. Is that ok? it's a flat fee after all.

In other words: "If I notice a bad actor, I block them" congratulations, you have solved all of the internet problems. That idea could be worth billions. Personally I just don't write bugs to begin with and therefore bad actors can't exploit them.
