While I haven’t encountered any issues myself, as a rather low level Steemian, I think the statistical % of users encountering this may be super low and thus we may be in the awesome position to think things through more and come up with a much more advanced solution, than merely raising limits.

I recently found @greer184’s excellent Proof of Worth concept and I must admit that is an awesome concept. It is a solution which could solve several issues encountered on the platform (think solo whales upvoting particular people to the hilt, etc...) and it could also be tied in with increases in bandwidth (when needed).

When looking at Sola.ai, they charge a fee for posting and each further post within the same day is more expensive. There are also daily login bonuses. Such solution could be part of an initial on boarding period of x days/week or until a certain amount of rewards/PoW/SP is reached, in order to throttle the initial eagerness to earn. EArn because of quantity, not quality.
