-1. One of the ways I made all my money was leveling up accs and selling them to people too lazy to grind for themselves. Also, people will continue to get scammed, so it doesn't solve anything, it just makes it so both parties can get banned, so basically people won't be able to even say they got banned.
I see no difference in trusting someone with acc selling than trusting someone with ZC selling. You take the exact same risk, just in a slightly different way. And if you're not smart enough to change all the acc info, that's your mistake, not Zylon's. So if you wanna ban acc selling, ban membership selling and ZC selling, too (just using that as an analogy, banning any of these is a bad idea for various reasons)
