If i use PokeGTS.us to get an event pokemon that I missed will their be any repercussions? Can i get banned from the GTS, or my device flagged or be prevented from trading/migrating or something like that? An answer would be greatly appreciated. Thank you.
No, you should be fine.

Why can't I think of anything else to put as my avatar?
i'm told(by guested) that the game registers you as having traded with yourself if you use a gts program, which is kind of a problem since that shouldn't be possible. i know pokecheck has some kind of provision to handle this, but i don't know what pokegts does about it.
as for what would happen because you were recorded as having traded with yourself? almost definitely nothing. just saying, it's there.
