Today I became a victim of several (uncommented) downvotes, 6 posts got downvote. I suspect this was happening for personal reasons only. My question is now how to deal with that. It is clear that I never will get any response if I just ask about the downvotes in the comment section of the questions/answer in question. Ignore? And is there a mechanism to undo this loss of reputation?
Your questions are covered by the Stack Exchange FAQ:
and in the Help Centre:
I would say the best thing you can do is to improve the quality of your questions and answers.
By the way, I would also encourage you to avoid:
- Asking for upvotes in comments
- Unnecessary minor edits to your posts
- Repeatedly unaccepting/accepting answers
These actions are just noise, and may even be encouraging the votes you are complaining about.
