So what exactly do you need to do around these lands to get a scammer tag? Send a video from the Bahamas while drinking a pina colada with a little umbrella that says "Haha! I scammed you, you gullible idiots"?
I mean, seriously? Do you guys want a signed, notarized meas-culpa, written in blood?
No you just have to be an idiot and make the forum administrators lose bitcoins. If you are popular and can claim ignorance, then you are free to scam.
