Help stopping a specific user from reporting posts and comments

I mod r/Habs and am a bit of a well known user I guess. Well known enough to have a guy who goes out of his way to report posts and comments of mine and call me homophobic, racist, and other varying types of insults.

I know reports on posts are anonymous, but obviously this guy needs to stop because he is abusing the report system to harass me. I was hoping you guys had a solution.
