...The things on the forum which encourage spam are allowed mainly because it's part of the forum's mission to be as free as possible. ... I am willing to take this sort of action, but only as an absolute last resort. It's always preferable to handle these problems by reshaping the environment to make them non-problems, rather than removing some freedom.

Limiting newbie participation is very harmful for a community. .... people with nothing better to do, scammers, get-rick-quickers, etc. Having a permanent newbie jail policy would improve things a lot in the short-term, but would end up being a fatal poison to the community...
So what I understand is - it's up to the members to decide if they want to buy into a scam or not. Members are adult enough here. If they lose money or fall in the trap then it's their own mistake.
In my personal view, if a website/service provider ask ID for verification and a person verify the account with his ID and then sell the account to another person then both seller and buyer are equally scammer.
I do not think I can create two paypal account with same ID. If I sell my paypal account then the other person is basically using my identity. If he do anything illegal then the authority will charge me. So I don't think when these people are buying an account thinking the account is the person's who is selling them. They are actually buying these accounts to sell it to someone else and these sellings will continue without no actual use of the account. So in other words:
1st seller scammer -> 1 buyer scammer, he is now 2nd seller -> 2nd buyer scammer, he is now 3rd seller .... it goes up to nth and nth+1
