Quick update on this, I made a short video about this topic because it affects all TCGs, my experience has definitely changed how I attend events. You can find on my short video platforms, twitter can be a little toxic so I'm not comfortable posting it here. Thanks!
I'm gonna do an actual post or explanation on how I was treated at ygo events at the end of 2023 because thinking back now it genuinely scares me. Because people NEED to be calling out their friends when they see things like this. It's the only way it'll get better
