How is this service so unusable? All I wanted was a Taillow for my Dex, since they're a pain to look for in hordes so I figured using the GTS would be easier.

"It's just the 3rd Gen Pidgey, right?" My naive young self said, "I'll probably only have to trade off an extra starter I got off of Wonder Trade, or something of that ilk, right?"

Surprise! All of the offers are:
>Darkrai
>Latias
>Mew
>Mew
>Mew
>Latios
>Mew
>Mew
>Darkrai
>Mew
>Mew

"Well, that's okay! I'll just turn off the silly kids asking for ridiculous legendary Pokémon with that nifty filter!"
>Suicune
>Suicune
>Entei
>Suicune
>Entei
>Entei

"Okay, I suppose those technically aren't Legendaries, but it's still a stupid trade that no one is desperate enough to make. Alright, fine. Besides those, what are my options?"
>No search result was found.

Am I missing something here? Why are there so few rational people using the GTS?
