If I feel like a certain user is harassing me, editing my answers, downvoting my answers, closing my questions, making offensive and condescending comments, or anything like that; what can I do? I have read the relevant FAQs:
Who are the site moderators, and what is their role here?
Why and how are some questions deleted?
What if I disagree with the closure of a question? How can I reopen it?
But what I am asking about is a specific person who seems to be "following me around" the site. I only have one answer and one (closed) question on Programmers.SE, and both of them have positive reputation and upvotes, apart from this single user who is consistently harassing me. Is there something I can do to report that?
