I don't think you're a scammer at all. You're just an unethical sleeze who profits off of other people's mistakes.
The scammer tag isn't appropriate at all, but there is no "Unethical Scummyfuck" tag.
P.S. I voted "no" because you're not a scammer. You're just unethical and the more people whom you draw attention to yourself will only confer with this.
