I dont buy plat. It's ridiculous to spend your hard earned money on something that isnt real. (Paying to play the game is real world entertainment.)
To any of you who buy plat: Just remember that you're one of the jerks fueling this problem. If players dont buy plat, people will not be selling it. You're allowing these people to spam your fellow gamers. You're saying : "I'm a liar, and will not abide by the terms of the EULA that I accepted when I started playing".
