How many times can a moderator or super user vote a user over time? I know if I go to another user's profile and up and down voted multiple Q&A then the votes could get retracted as serial votes. So is there a time between votes that would not red flag? I believe I may be serial down voted slowly. Can there be a cap to how many times one person can down vote another? I feel I ask relevant questions but they are not a smart as they are.
Voting by moderators works exactly the same way it works for other users, and moderators are subject to the same voting restrictions as other users.
The serial voting detection and reversal mechanism is an automatic system process (no human intervention) and it works the same on moderators as it does on unprivileged users.
Finally, the system provides some information to moderators on long-term voting tends and cliques which allows for possible human intervention in cases where some user attempts to slip in a slow trickle of votes directed at another user.
Also mods can't vote more than once to a post. The only possibility to vote multiple times, if you use multiple accounts for the task. Doing this "correctly", the SE has no way to know, that they are socks. But they are watching quite sophistically the cases, where they aren't done correctly.
If you want to check, if you are serially downvoted, you can do this by sorting the reputation changes in your profile page by time. By default, it is sorted by post. Click here.
The downvotes in short time, but to your different posts, are coming probably from the same person.
What is visible on your reputation changes, that you aren't serial downvoted, but somebody doesn't like your posts.
It doesn't need mod privileges to serial downvote somebody.

In your place my main problem wouldn't be the downs, but the closes of my questions.
