No. I will note though that half of the people I banned for downvoting on the old lemm.ee instance didn't even have a comment history. Their accounts only existed to downvote. Others had been banned repeatedly by other communities for mass community downvoting. But even if they did, I would've still banned them. They were constantly downvoting new posts posted to the community and had no engagement with the community in comments or posts. How they may have behaved outside of it wouldn't have come into it for me.
