SFR should transition to upvoting posts through the Steem engine tokens... It's in process, and a year ago there was no decent SMT stand-in. Now there is.
If we want abuse to decrease, we need incentivize abuse fighting. Right now, the best to do that is upvotes (sadly, on automated comments).
I suggested that the ratio between the flag value and the SFR upvote should be significantly lower (in the 0.5-0.75 area), but I am in minority opinion. Although, at the moment, the goal is to actually popularize abuse fighting, so a 1:1 ratio has some benefits in the short term.
It will take some time to reach perfection. Please be patient
