Wiping out abuses 100% isn't realistic, but that doesn't mean we shouldn't try. I think one additional benefit of continuing a campaign against these types of abuses is that when they become effective enough the types of scammers that might come here for easy money will begin to shy away when it becomes more widely known that there are groups of people (and even bots) that effectively make it not worth their time. It is good to see that there are some here with the power to affect change to actually do so and try to make Steemit a better place for all of us.
