I quit a while ago. I already completed my Pokédex on Sword version and found way too many hacked mons on Gen 7's GTS. It's just not worth the hassle anymore.
I quit ages ago. I'm never even planning anything resembling a return and anyone in their right mind would quit if they are still involved in older gen trades at the moment, It's getting to be 99% hacked shinies with max IVs and EVs in every stat or with hacked values in a single stat.
