The forum doesn't moderate scams:
A: Possible (or real, not for me to decide) scams are not moderated to prevent moderator abuse. If we start picking out which ones we call "scammers" and ban, we would make a lot of decisions based on biased opinions.
There are plenty of exposed scammers out there that are still able to post freely. The community does a good job of dealing with this through the Trust/Flag system though, so it's important that everyone utilize that at least to some degree. Instead of asking mods to nuke him, which is probably unlikely, it might be more helpful to support DarkDay's flag instead.
But yeah, all this really teaches us is to not trust strangers on the internet.
