This is possible because he created 48 threads and spammed all over the places. His account is banned and actual count to the post is reduced to 0. Now his posts are all shelved but they exists actually and so he home page shows 48 posts but not on his profile.
Again, I fail to understand this : So, is H3ll M1nD3D a guest or a member ??? And, can guests make posts ??
No Guests cannot make posts but if some user makes a posts and for some unavoidable reason we delete that user then the posts by that user goes into Guests posts and remain on the forum. Can you share the url of the thread here.
