Just adjust the criteria accordingly. There are some high values you could set there so it is pretty much always visible.
However, please note, the use case for the Spam Cleaner is only to deal with a relatively small amount of content. It isn't supposed to be used for cleaning up thousands of posts from established members. It's extremely unlikely a well established member would suddenly become a spammer, so generally the spam cleaner would only need to be used for newer members with not a lot of content.
