Although proof is saying you are more or less right, I think thay guy didn’t have scamming intension, instead he did a mis quote as you know it’s fucking hard to use SMF for people from this century. Not many people are used to use SMF forum and they make some mistake. I think it’s wrong use of quoting.
You might be right but I think it is a good way to scam. If the user would be a legit user then there was no reason to quote a post and even the post which was posted a more than two years ago. It is a proper chance to be scammed.
