I don't care to dig around in this particular pile of manure too much; some very basic "let your fingers do the walking" reveals a B-level Brazilian musician; none of his other social media or web site in ANY way references Steemit, or an interest in cryptocurrencies. In fact, his name is not affiliated with cryptos or Bitcoin ANYwhere.
The fact that he seems to write a lot about personal development is also "off topic." Meaning, out of character.
The only reason I even got curious enough to poke around a bit was the possibility that he was "big" enough to have a PR manager running his Steemit. That's even iffy. 90K likes on FB and 220K followers on Instagram is not "big time."
The other thing that's a little sketchy is that IF he were genuinely sent here as result of "lots of friends and colleagues," he should have a disproportionately large number of Brazilian (or Portuguese language) followers... and he doesn't. So there's that.
And therewith endeth my thumbnail investigation.
I thought it was quite a thorough one! :0)
My friend is a B level musician too and can barely afford a bus pass, look at the cost of the paid upvotes, thousands of dollars on each one, and that's at a loss, you lose money on paid upvotes.
