I found this Pokémon being traded online, there was also a shiny Galarian Articuno. I am curious if this is legal, can it get me banned? btw, no. I didn't trade it

sometimes during mystery trades i get these shiny legendaries from weird websites. what do i do with them? is this even allowed? : r/PokemonSwordAndShield
