Hi, it was me who casted the downvote to your post, don't slander acidyo if you don't know who did what.

Buying votes is buying votes, no matter what the purpose of the rewards is for.

Oh and by the way, I don't recall anyone calling it a scam, just a general comment at charities on steem (which 99% of them have proven to be that, scams), but nobody called it directly to your project, at least not from acidyo or me which opinions represent the project.
