This wasn't a spam post. It was an invite thing.
The idea of exposure is nice...but that's not how it's worked out. At least not so far. The concept was pitched to me as giving good content creators a chance for more people to see their posts...and hopefully helping to level the playing field on Steemit.
I'm tired of seeing people post a picture and get $200 worth of upvotes, when others put hours into their post and get next to nothing.
That said, so far it's worthless from what I can tell...and only making Steemit whales richer. I wouldn't recommend it.
