On the GTS people ask for fair legend trades.... sometimes I need a legend like Reshiram for ORAS's Kyurem.... but I don't feel like beating a game going to catch a legend then waste (more of) my life transferring. So I go onto GTS and see a perfect trade, some idiot is trading a lvl. 100 Shiny Reshiram, for a Celebi... I don't care for Celebi so I trade it only to get that box.... that one BOX.... you know which one, the one that says I can't trade it because it has a ribbon! Couldn't they have given our game self a better reason to trade it? Do people know that this is the case and are being jerks or have they never seen THE BOX? (I don't care it may be hacked so don't even.)
There could be multiple reasons like....
Probably the last one, it's level 100 and shiny, who wouldn't want it?
These people are just trying to be jerks.
The Reshiram also may be hacked btw.
