I'm kind of surprised at how most of my former co-workers will not put the common name of the company (which is not offensive or profane) on their resumes and put the legal name instead (the legal name is pretty generic-sounding). Some have even requested that I change the name on my LinkedIn profile or mark it as "I worked with so-and-so at different companies" so they won't be directly associated with it. Maybe it's just a scarcity mentality thing; they're worried about turning off potential employers, but when you're constantly getting contacted by recruiters I guess it's hard to feel like it's a disadvantage.
