In the past 7 days, I have received 9 downvotes (on questions that have been otherwise positively received). I suspect someone is systematically downvoting, but doing so with a large enough interval between downvotes that the system in place to automatically recognise such behaviour is not catching it. I see this sort of thing has happened in the past. Is there any way to confirm whether it is happening again, or whether it is just a coincidence?
We heard back from Community Management, who determined that it was indeed a case of targeted downvoting. A message was sent to the account doing the downvoting.
I learned something I didn't know before: by software design, any reversal of votes from one account to another reverses all votes, and not for example just votes within a specified time period. In this case, there have also been upvotes from this account to varkor's, in fact more of these than downvotes. Since a vote reversal would therefore result in a negative net change to varkor's reputation, it was decided not to apply the vote reversal.
There are no plans from the software developers to make any changes in this regard. Anyway, I thought that users might like to have this information. (To varkor: if you would like to have the votes reversed anyway, please write to the moderators, [email protected], and we'll take it from there.)
That's frustrating, but I'm not sure it counts as "serial downvoting", which I understand is something the software catches, when one user is up/down voting another based on the person not the content. Here's the language around downvoting:
When should I vote down? Downvotes should be used to indicate issues with quality, effort, or accuracy of a post:
Downvote questions that don't show any research effort or don't contain enough information to be clear and answerable. These questions may also need to be closed.
Was there a theme around the contributions of yours that were downvoted? Like, if they focused on some specific concept?
In the meta post you linked to, the OP said "Clearly someone is mad at me." Do you have some reason to think that this collection of votes is personal rather than based on a judgment about clarity or research effort?
Again, sorry if that's frustrating. If it helps, I think a lot of users have experienced this. I know I have. My solution was to just care less about reputation and downvotes.
