Forcing people to do stuff rarely works... Facebook has a huge radio box with 20 things to select when flagging if I'm not mistaken. Lol, this brings up a whole new potential world: #Flagtags.

Anyways, you might just end up with more comment spam, which is why I don't think they'll tweak it easily. Now, the option to ignore someone's flags IS a good idea. Even better would be able to score people and posts yourself. Have a parallel steemit world where you apply your own set of weights or multipliers to people. Just imagine that as a #feature.
