Marco got attention for this post because he put it in front of us... He tagged a bunch of us on Facebook. If his Steemit reputation has risen quickly, it's only because it's coming in line with his real reputation, and he's taken the time to promote his work, and of course because he had a little luck in having some friends who were already on the platform. Reputation works on a logarithmic or quadratic scale, so it's quite easy to rise from 25 to 35, but harder to rise from 35 to 45 and so on.
I know Steemit isn't perfect, and a lot of the time good content can slip through the cracks. Of course people who are well-connected do tend to get their work recognised easier. I know it can be disheartening if your work isn't recognised. I don't think it benefits you or anyone else to call it "stacked", or to call people's profiles "fake". This is a social media platform, and making connections counts.
People here have worked very hard to make this a site where people are polite, respectful and uplifting, where you're even free to disagree without being attacked, as happens on so many platforms. I would love it if you decide to adopt that vision as your own.
Good luck and have fun.
