As another user correctly said - you can edit.

I just want to add that this type of post can also turn out due to the fact that, due to their laziness, when writing a post, the user does not go to the last page of the thread, but quotes the first post, and when the tab opens, the user deletes the iterated content and writes his text. In this case, the name of the thread remains as in 1 or 2 post.
