Bots. I've posted many popular and unpopular takes here. Down always comes first, and as the bot votes evap into the ether, the true human take is almost always revealed after an hour or two.
This seems to have gone to -10 and then went up according to this, which matches what your comment had said that you were seeing -10 on your android.
Edit: (actually it had gone all the way to -15) and seems that this website has been still stuck at -8 upvotes at the moment of this comment and this link has also been the proof for me to finally see/confirm this as the submission now has positive upvotes.
It is hardly a satisfying answer, but I haven't the foggiest what caused it. I submitted it the same as I've submitted many other submissions in the past.
Perhaps some kind of auto-downranking system used for moderation of specific topics or thigns (without explicitly removing them) that accidentally targeted said post? Just idle speculation.
Now, the post linked itself has been upvoted so it doesn't have negative submissions but it seems to have had been the case.
I don't quite understand how posts can have negative points :-/
A hunch but maybe a post which got confused as comment id of some other comment which got downvoted so you had negative karma, but I am unsure of this spooky action at a distance. It would be really interesting to know the reason behind it.
I suspect the same is happening for some others too, based on the comments on that article.
Bizarre!
Update: 2 minutes later and the link from the hn home page now correctly leads to: https://news.ycombinator.com/item?id=48106316
Never seen that happen before.
The normal behavior for link posts in HN is that the title takes you to the link address, not to the post address.
To enter the post address, you need to hit the "discuss"/"x comments" button.
So, what you describe is HN working as expected AFAICT, it's just a bit counterintuitive because it's an HN post linking to another, which is uncommon
Doesn't appear to be negative anymore, but here is what it looked like: https://vale.rocks/micros/20260512-0652

Is that people looking at the new page and seeing/upvoting your post and then it falls off the front.
If anyone's interested, here's a list of undocumented HN features/rules (although I don't know how up to date it is): https://github.com/minimaxir/hacker-news-undocumented

Although negative profiles have always been a thing.
You cannot easily downvote submissions, in fact I'm not even sure if you can.
