Someone using the email name "ping pong" posted a badly-written advertisement for nature photographer Marc Adamus to this Guestbook. WC recognizes that all photographers have to make a living. But this is WC's site, and it is discourteous, at least, for another photographer to advertise his wares on WC's site.
So the Guestbook entry has been deleted.
Oh, and WC knows Adamus's work, and doesn't agree he is "a greatest adventurer [sic] and landscape photographer on earth at this moment ."
