Not to toot my own horn too much but I do believe what we had with @steemflagrewards (with @hive-dr) with the broad net we had working against comment spam and the myriad forms of token manipulation on chain could have been so much more.

It would never scale. It doesn't solve the problem because the global reward pool is a bad idea. There's literally no unified standard for judging all content except in obvious cases.

It forces these "groups" to play perpetual "whack-a-mole" on the same target. Guess what? You can't stop them from earning curation unless you want to wipe bystanders out.

Tribes (and SMTs supposedly) can allow or disallow the flow of rewards without these pointless bloat that don't go anywhere.

No global reward pool means:

Less pretense "content creators"
Less pretense "curators"
Less pretense "social" bullshit
Maybe more focus on the actual economics

Some people tout the "millions of transactions on Hive" a day, but they are worthless metrics, especially for a group of people we like to dangle "genuine interactions" as a catch phrase or ideal.
