Just remember, it is up to you as the trader to know what is shiny locked and what is not. There is so much misinformation out there about what is locked and when that changes. And it does change. Lunala and Solgaleo are both shiny locked in S/M but were an US/UM event giveaway as shiny. Cosmog and Cosmoem are both still Shiny locked and not availble.

Educate yourselves and you will not be scammed.
