Definitely the recruiter. They destroy resumes. Best/worse experience - walked into the interview and the interviewer asked if I preferred to go by first name or last name. I said I'm happy to be Alex, but don't hugely mind. He said - no "First Name, or Last Name", and showed me the resume. The recruiter had stripped off header, slapped on theirs, with logos and all, and forgotten to change their boilerplate, so my name on the resume was literally "First Name Last Name". Luckily I had a print out of my real resume with me to show him, and that I wasn't the type to submit a resume without my name on it. They'd also ended up putting 1 line onto a second page, which is minor compared to missing off my name, but pretty annoying given I'd put a fair amount of time into coming up with a nice 1-page resume.
