I don’t think this sort of advertising would result in a takedown notice either. More likely it would be used as a honeypot or it’s participants investigated to see what other shady activities they’re involved in. This site though expects the community to take the responsible approach and not encourage or support users who would engage in the advertising of money laundering activities for their own benefit. Is it illegal to advertise? Probably not. Is it unethical and leads to scammers feeling empowered here, in my opinion, yes.
