I appreciate the intent; to allow advertisers. That would be a way to get content creators to be rewarded a bit more...

1 - a big part of the appeal of the platform is the lack of advertisement (beyond self-promotion)
2 - People will abuse the advertising system to maximize their own potential
3 - would not mitigate some of the issues of influence and rewards

Anyway, point is; should think carefully before starting down this path, it might solve issues but has a solid potential to create new problems.
