I think any changes to the name your mum and dad gave you are suspicious. The only world this is okay in is celebrity world, authors don't take on the identity of their pen name as celebrities do. The blogger Perez Hilton gets on fine doing the celebrity gossip stuff he does. I doubt he would get a regular job with the name. So maybe Spider Mann has got it wrong, if he went full celebrity all would be okay.
