Well, isn't the whole point of the RP that your being blackmailed into doing what The Presence wants you too? 

as charming as Joe is, he seems to be in complete control of his life and his environment. The Presence doesn't really have anything on him. What, is it going to expose him as a shape-shifting demon? Oh no, what a terrible thing for old Joe. It's not like he's a shape-shifting demon who can literally just disappear off the face of the earth, living as someone else until he goes back to stealing.

edit:
the presence may be able to find him, but for how long are the police going to follow it's leads? surely they would get sick of getting anonymous tips that Joe has shape-shifted in an old grandma now.
