Recently, I posted an answer to a question on SO, about 5 seconds after another user posted a very similar answer. For some reason, that post was downvoted, but mine wasn't; they were almost the exact same answer.
Anyway, they posted a comment more or less along the lines of "How come my post was downvoted when the other post wasn't", and adding on a bit more to insinuate that I had tactically downvoted it. While that is a fair conclusion to come to, I'm not sure if it's OK to post a comment with that. I won't name the person(that would go against the point of this post), but in general, what should I do in this scenario, as it may trigger serial downvoting or other repercussions against me.
I see a few possible courses of action
- Upvote and post a comment saying I didn't do it
- Post a comment saying I didn't do it
- Flag the post as offensive or possibly not constructive, depending on how offensive it is
- Upvote without saying anything
- Do nothing
I took option 1, since I wanted to clear my name, and I probably would have upvoted the question anyway. Is that the correct course of action? What should I have done if I had tactically downvoted him?
