Discourse affirme que quelqu'un n'a pas posté pendant certaines années mais a posté à une date différente

"Last post" message apparently wrong

The message is about the user last post before the post it’s attached to. It means that before the post on the picture, the last post was five years ago, and it’s meant so other users can react properly to either a new user or an old timer coming back.
