Seems like one solution could be to limit the transition from everyday users using for social reasons to brand/content creator users using it for monetisation by capping or limiting the social graph (e.g. a cap at 150 followers/following/friends/whatever you call them). Brands and content creators would have no incentive to join and devalue the network with constant marketing and high-effort posts when they can only reach a maximum of 150 people. I thought I vaguely remembered a similar idea, and a quick Google search only returns a brand called Path (no longer operational). Maybe there would be renewed interest in the idea.
