Dang, I was hoping for one to one, but I don't know which exchanges still carry sbd/hbd, if any.

Bittrex probably, but I'm using binance which does not have hbd. Would hive -> hbd be useful for you?

I'll soon be out of steem, they shadow banned me.
I don't appear in my own feed.

I was just hoping to go from sbd to hbd as close to one to one as possible.

Sbd -> steem -> hive -> hbd
@swapp.app should soon allow this.

That can be done on the internal markets, it's a nice to have, but not critical, imo.
Direct exchange might be too easy to bot and abuse.
