I'm playing this game long-term. I believe that Steem is just scratching the surface of its potential. We could rival Medium in a few years, if we play our cards right.
Some people think of steemit as a medium, some as a fb. I think it's a bit of both.
I've just checked your blog and wallet, saw your post about this initiative and your holdings. You've got a ton of sp and you can make a real difference. I'll be the last guy on Earth to tell you how to use your stake, but I'll invite you to think about the other approaches you can take and see if you can get more bang for your buck that way.
Fighting the abuse is not the best approach in my opinion, sure, there has to be some effort to combat the botnets since it can cause a lot of damage, but these hustlers trying to make $5 with $75 investment are not that big of a deal.
I see that you're aware of the problems this initiative can cause and that you've limited your flagging to 50k sp accounts. So, if I have 50.001 SP, I'm safe. The problem is the backlash. There's no way a person can not take the flagging as a personal attack because it's very easy to produce a 100 more shitposts of the same quality that are not being flagged. So, you either have to flag all of it or accept the fact that you'll have people holding your actions as a personal attack on them.
Steem has great potential, but so do have many other projects out there. Keeping people around, engaged and invested is much more important than going after the hustlers.
With that in mind, here's something that works. Two things:
Autovote lists - most people earn nothing here. Very few make any money and the upvotes & rewards are seen more as some game points than the real money. I can give you an example of a guy that with a fraction of your SP did a great job and his efforts have produced a vibrant community on steem that's alive and kicking for over a year now.
Here's how he did it. He'd look out for the new users that are posting under his niche tag, and if he saw a genuine account he'd add it to his upvote list. He'd start you with a small upvote and if your content started to improve that % would go up... A regular, even if worthless in the terms of $$$ upvote and the path forward has created a community and kept it going to this day.dApps - Have you tried Actifit? Those posts do look ugly/spammy, but there are real people posting them and having some fun. That's the app that has an effect on people's lives in the real world. It motivated me to start walking, not because I'm earning $$$ from it, but because there's a community around it. It's fun, too. I see a friendly banter going on, people trying to outdo each other... That's the kind of thing that's worth supporting.
I guess, what I'm trying to say is that this game is about the people, not the content, having their attention and getting them to spend their time around here and not on some other project. God knows there are a ton of them out there, and that's why I think it's better to build up this place than to police it.
