If posts are spam, let's report them and the spammer will come to a ban soon.

A little bit beyond this case, you can see a user makes a series of post but if these posts are good in quality, it's not a spammer and no issue at all. Assume he composes these posts and when are ready, he releases it in a series. This style is not common but I would like to give the example to show that quality is key of deciding a post is spam or not spam, should be deleted or kept and a poster should be banned or not.
