PS - i just found out how to turn off comment rewards

it only works in https://www.proofofbrain.io/ front end - it's the only one that will do this

go to settings and turn off both post and comment rewards

from then on you can do posts on any front end and the rewards will be off

but for comments you have to do them on that front end - pictures don't work but the comment rewards are off on all front ends, so no more comment downvoting
