Hi Hector, and welcome to SpiritKeep!
If you are serious about becoming a ghost hunter or a paranormal investigator, you need to realize that a name like 'Graverobber' is not taken lightly in these groups. People who deface, destroy, or take things from cemeteries, or any other haunted location are not serving the best interest of the ghost hunter or paranormal communities. It is hard enough to obtain permission for investigations at some of these places. A good ghost hunter/paranormal investigator takes only pictures, and leaves only footprints.
If you are truly interested in learning about hunting ghosts, then I would suggest that you start by reading the many forums here that pertain to that subject. If you have questions, please ask. It takes time, research and experience to learn this, and it isn't something that anyone can tell you in a single post.
