The following are considered hacked and banned from PC's Trade Corner: Shiny 10 ANIV events, certain shiny GBA events, Pokesav'd Pokemon, and fake events. They have been removed. Notify others if you have traded the hacked Pokemon.
There is no reason for you to have an absurd amount of hacks. You have plenty of resources. Use the Trade Corner Rules and PC's Official "Check My Pokémon" Thread to your utmost benefit. If you ever need help deducing a Pokemon's legality, feel free to ask me. Thank you.
