I am sure they could find a way to find the abusers if, and I do mean “IF”, they wanted to. Myself, it would be great because you have to bring new players in. I’ve been on WT since it dropped on console. Bringing new guys in even recently. It would be handy to gift them SL so the grind,( which has gotten progressively harder over the years ), doesn’t make them want to quit. Which I see more often than not.
Could restrict it friends list for 1+ month and had to play 10 games with each other or something. And like others have said add a colldown to it like maybe 2 times a month and only 1 mil sl per trade. That should be enough to curb selling.
