Actually I'm not exaggerating, searching for a Piplup, a Turtwig, a Stunky, a Misdreavus, a Murkrow, a Glameow, a Ditto, and yes, a Spiritomb, each and every last one of them, someone wanted a Deoxys, a Mew, a Jirachi, and either a Darkrai, or a Shaymin in exchange for it, and I'm going to wager they all wanted them at level 100 as well since I can't see the levels in Platinum because of the GTS glitch. And by the way, even when I was in their "target demographic" I still didn't know anyone who actually played Pokemon besides myself. Also, why would I be saying I want WiFi for anything like the Underground if I don't have WiFi already?
As has been pointed out several times about the contests, if they do include the Underground, and they include an option to do it on WiFi instead of on useless local wireless, then just don't use it.
