One time when I went to the GTS, I was looking for a MEW. I checked out all the trainers, and one was a PIDGEY named Mew or something like that. Doesn't TPCi notice that it's not a real Mew?
Also, when I was searching for KYOGRE on the GTS, someone had a shiny DARKRAI and wanted a Lv. 100 DARKRAI. When I got my Darkrai and hit 'trade' it told me that it was traded to another trainer. So I searched again, and it was still there. I repeated it for about three times, and never got to trade. Why?
