Would you mind elaborating? I didn’t upvote, just curious if it’s a faulty fraud detection..

Why do you suspect foul play here, considering the OP is claiming not to do it?

Edit: and thanks ahead of time!

I am not doing anything :(

A bunch of fake accounts upvoted the submission. I'll take your word for it that you didn't do this and mark my comment offtopic.

If you really weren't doing anything of that nature, then I'm sorry for suspecting you! Many people are trying to manipulate HN in this way, so we have to guard against it.

Is that also the reason it went from first page to 2nd?
