Is there a good reasoning why this is the way here? Isn't it staff job to keep these forums in order and safe?
To prevent abuse mostly. Yes Ponzi's are often bad, but if we start removing them we would have to remove other proven/most likely proven scams as well. This can get really tricky, so we stay out.
Why is it better to not even try to remove the obvious scams? You could do a few mistakes here and there, still I'd say it would be worth it. Of course it requires work to moderate for scams. Anyway wouldn't it be better for all of us if these forums had more utility?
To prevent admins from calling me dumb, I let you know I understand this is not a simple decision.
