Ok, here's proof for whoever downvoted me.

I made a new account, wrote a message, upvoted it with my current account.. and no change in points. I never see any message become black or "less grey" after upvote + refresh. It is a no-op for me.

HN likely does something to prevent vote manipulation from using multiple accounts coming from the same IP. That doesn't exclude the possiblity that your account had a flag to desregard votes before. I personally dislike this kind of hidden moderation like shadow banning. I know people will defend them saying that they are needed to deal with spammers but that does not make them any less dishonest when they invitably affect genuine users.
