Moderators aren't notified about spam-deleted posts. Moderators can't specifically search for them. Moderators can search for deleted and locked posts, which shows posts deleted as spam and rude/abusive along with other posts. If you feel that more should be done on a specific user/post, then you should raise an "in need of moderator intervention" flag and explain the situation. There are user-generated systems which can help bring such deleted posts and users to moderator attention, such as the Charcoal project (I'm an admin), but there's no automatic on-SE notification. — Makyen 16 hours ago
