Sorry to hear this, @focusnow.
I'm aware this is a huge problem all over SteemIt these days.
You could try asking in Steemcleaners Discord channel, but if I remember correctly, they don't cover downvotes.

Maybe you could ask @r0nd0n in the @freezepeach Discord server (you'll find a link at the top of the @freezepeach profile page). They deal with downvotes daily... I think that's the best place to get solid advice.
