Is it possible that other accounts steal submitted links or posts?
I just had this experience with my paydevs account: * On 2022-10-29T12:43:45 I postet https://news.ycombinator.com/item?id=33383563 on my paydevs account, which does not show up in the stream and HN search * On hour later, on 2022-10-29T13:43:02 the user https://news.ycombinator.com/submitted?id=pabs3 published the same link with a different title: https://news.ycombinator.com/item?id=33383972
Is this normal on HackerNews?
I suggest you ask at hn@ycombinator.com
It does seem odd.
Stories on the web aren't your personal property that only you are allowed to submit. Get over it.
I looked at the data and as far as I can tell it was just a coincidence that the other user submitted the same link.
We banned your paydevs account though - it's against HN's rules to use the site primarily for promotion (https://news.ycombinator.com/newsguidelines.html), and that account was not only doing that, it crossed the line into what the community here considers spamming. That's why your submission of the link was killed.
