It doesn’t matter whether you or someone else already posted it. Happens often that something gets posted multiple times because of how Lemmy works.
Nobody else is posting my cat. Lots of people posting this news. It’s redundant and old already.
And to directly comment your other comment. How should one know it is your particular cat and not a cat picture that’s taken from the internet? Not that, that even matters.
The other commenter just said that, I guess because your comment is redundant and not necessary. You posted it or seen it before? Okay, fine. Scroll past it or hide it.
It’s redundant and old already.
To zoom in on this, it is actually not redundant and old for other people. Perhaps for you yeah, but some people might not have seen your particular post and will see this one.
