If this were possible, it would bring about great improvement to the majority of active little fish. Being one, I'm in contact with dozens of complaints every single day from the ones who comment the most.

These are friends who would give me good feedback on all my posts in the morning. Now they have to cramp all their usage in the night because days are dead with -10/-50 kB available. (And who's to say spammers don't do the same?)

We have to give priority to quality posters, regardless of size. I think bandwidth delegation would solve a big part of this. (It could even be added to your smartmarket initiative.)
