Can you accurately describe this 'bot mediated' downvote process? If this can be attributed to a particular person-path -IP address? (who instruct these bots), I am sure this would be something that goes against the basic principals of Hacker News and would be of concern at the highest levels. I can understand the 'flag' that can be attributed to various 'ist comments to ID and get them removed - but downvotes can be misused and bypass valid dialogs. I make comments and get up and down votes. Often I get downvotes for correct analyses, and I also get upvotes for POVs I feel are also technically correct. I never deal in 'ist comments as they have no place here and are properly flagged. Could some of your comments be almost flaggable and so got a downvote instead of being flagged? One would expect flagged comments to be admin assessed for guilt and be deleted or even unflagged at the admin level - I realize admin time is scarce and there may not be time to waste on this - let them fall to the earth....
