Its buying votes. you bought me steem up votes derived from the daily reward pool by buying me SBI tokens. Not saying its right or wrong - just what it is.

My view is if you buy SBI tokens, you should get votes in SBI tokens which later you could trade for steem on the market if you wished.

thanks for the SBI, but i had them cancel voting on my stuff awhile back, got sick of my one word comments being pushed to the top and nobody to downvote them to where they belonged lol
