GTS Glitch? My Pokemon Fled?

Question

On my black version game, I went to the GTS and once I logged on it said:
>It seems your Ferrothorn has fled..

Answer 1

This is not a glitch. Your Ferrothorn is gone forever, sorry dude. If you leave a Pokemon in the GTS too long it flees into the wild.

I don't know if this is cause it was traded or if nobody wanted it...but from what I read you can't get it back. Sorry :(

Why is this even a thing?? D:

Read another source, and it said it's because Nintendo doesn't want to store your data for extended periods of time. Awesome! That'll show those hackers who want Level 1 Zekroms >:D

Lol well what about the people have perfectly fine pokemon that they don't want to lose... forever?

Well tough....Nintendo doesn't have time to deal with everything.
