For some time now, the main forum I moderate has been facing problems with downvote bots. Recently, these problems have gotten significantly worse. I am moderating the r/Syria subreddit, and now, regardless of who posts a topic or leaves a comment, the content is downvoted just because it is Syrian content. (You know what is happening in my country, Syria, and you are aware of the political complexity there. This complexity affects all foreigners who intervene to combat content that doesn’t align with their political views.) The content is downvoted at least twice within one minute. I know it’s not just happening to me; I’ve noticed many users talking about this problem and mentioning it here before. Honestly, this is affecting the morale of the forum.

Is there a way for the administrators to run a program or implement a mechanism to prevent or ban accounts with an abnormal positive-to-negative voting ratio? Of course, moderators can't see who is downvoting, so we can't take any action.

Is there something I'm missing here? Is there anything that can be done about this issue? I need help.
