Personally, I don't think we should raise fees.
Now, if we must, I think increasing the fees on bandwidth is the way to go.
Penalizing new account creations can work in the short term but I don't think it's a sustainable solution.
Penalizing transactions (if I understand correctly) will discourage voting, following, unfollowing, etc)
Penalizing bandwidth (if I understand correctly) may prioritize longer content and incentivize people to create better posts.
If the goal is to increase the quality of the posts, then bandwidth may be the way to go.
here's a point for you :) thanks for your opinion
