Copycats, I think.

On the MuchMusic blog, you'll see that not only is there someone using the name Jimmy Page commenting, but also someone using the name John Paul Jones, someone else saying they're Robert Plant, and someone claiming to be David Coverdale. Now there's also someone using the name 'Ghost of John Bonham'.

Sounds fishy to me.

I also think it's cruel to use a name like 'Ghost of John Bonham'. You don't do that. So many people admire the late John Bonham, myself included. It isn't fair on his family to do something like that.
