I go around on the gts every once in a while (i normally do GTS negotiations abbreviated gtsn And I would find these offers for ridiculous Pokemon like hack Pokemon in all basics. I do not know if this is just an accident or is it on purpose so they dont have to see that Pokemon. Is there a way to get away from these offers where the people want ridiculous Pokemon and their impossible to get (without hacking) levels???
Nope people do it just to show off their Pokemon and all you can do is stare.
If your looking for specifics in a certain Pokemon then no. But I suggest changing the little specific things. Like let's say you wanted a male Buneary at Lv.50 you would need to change that. But other than that they're showing off pokes mostly hard to catch pokes and shinies. So stay away from them.
