I haven't had any issues with it. I honestly don't know how locked down a Facebook account can be these days so "ghost account" may not be the right term.
I have my name and a profile photo on there, but I've never posted anything, don't follow anyone, and all privacy setting are set to block me from search, feeds, etc.
I've only ever had one person block me after messaging about a car for sale, and I couldn't say whether it was because of the account or the questions I sent made them think I'd be an annoying buyer to deal with.
