Shouldn't a Ghostwriter be a Good Writer?

If you're anything like me, you only read Canadian magazines when you're at the dentist's. So recently, in for a cleaning, I checked out Macleans. There was an article by Rebecca Eckler, about the many people online who trash her, in which she wrote the following:

Along with trying to monitor what seems like every second of my life, they
have posted lies (for example, that I have ghostwriters).

One thing I would never think about Eckler is that she has a ghostwriter. Because, you know, isn't the idea behind hiring a ghostwriter that they ought to be an at least adequate writer? (Just sayin', is all...)
That said, I agree with her overall prognosis of the situation in cyberspace -- there are a lot of people who stay hidden and simply go on the attack. They have, as she says, too much spare time. Heck, I am nowhere near as high profile as her (thankfully), and I have similar "anti-fans".
