I'm technically sin papeles, and have never had a problem. I don't work, though, legally or illegally. I have a right to be here, but just haven't jumped through all the hoops. I won't either, until this summer when my husband changes visas from student to working. Then, I'll apply again too. (I'm entitled to be here as his dependent, whether he's a student or an employee). I just left Spain this weekend (went to Istanbul for Semana Santa!) and came back in no problem. As far as I know, I get 90 more days. Sorry, I know that doesn't answer your question.
