This has happened to me time and time again. I post or comment and then I see a typo. I edit the text. Then I see another typo. I edit again. And now my post or comment has disappeared. It took quite a few times before I happened to notice the, laughably easy to miss, message about the post entering moderation and found that it had been rejected as spam.
Please, for the love of sanity, fix this broken forum so that edits are not detected as duplicate posts which might be spam. This is about as basic as it can get. Forums should not randomly delete posts when edited!
I searched for this and it is an old old problem. https://community.spotify.com/t5/Subscriptions/My-post-was-deleted/td-p/4750486
Why in the world have you not fixed this? A forum that randomly deletes what people posts is absurd.
