I have a Tampermonkey extension which hides posts after an upvote/downvote. Because of this, I'm voting on basically everything in my subscribed feed.
I do want to call out some concerns here. I'm not excusing op's behavior, but indiscriminate downvotes is the kind of thing I'd say we don't want here and I'd say you're both in the wrong even if one of you is farther down the path.
