It'd be interesting to see if you are banned
I did something similar, I traded away many Solgaleos, Lunalas, Tapus, etc. on GTS and nothing happened to me, it seems that as long as your Poke is accepted and it goes away, the most likely bet is that you're safe
ontopic: Not like I could use Global Link anyway, whenever I tried to access the site the thing just reset'ed on me and I wasn't able to use it, not only with me but this is happening with several users of the website, even for those who don't even know how to hack a Pokemon game, so I kinda gave up at using GL at this point, best thing to do is to ask someone to battle with you or just do a free battle on battle spot, seems like a better choice to do in the long run anyways
Connected and GameSynced normally: no ban, people.
