Ask HN: Are links and posts to HN being stolen?

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?
