Freebornsociety downvote with dust value. It is used to monitor downvoters and what is getting downvoted. Not related to u nor it takes alot of $ away from you.
Your problem is not freebornsociety who is following a downvote trail to monitor onchain activities.
It's not related to you, and it doesn't take much money from you.
It doesn't take much money, but take money and that's where the problem lies: "What authority does he have to downvote you and take pennies from you ? Who authorized him to do that?"
Fortunately/unfortunately code is law
