unless you are using the AR for cloning purposes, anything else to modify the pokemon or create a pokemon (ie giving it specific IVs/stats you want) or using wild/shiny pokemon modifier are considered hacked because they are not obtained through any legitimate means. From your description, it would match "creating a pokemon" so yes it is hacked.
lol skarmory still owes me a replacement pokemon for the Kingdra that he and Draco Meteor traded me for my shiny faraway Island Mew. Kingdra had 31 IVs in pretty much every stat...
