Basically, never ("Once a scammer, always a scammer"

).
The alternative of adhering to a removal request has merit, but the various possibilities should be considered, i.e. her scam profile containing :
1. Her photos only: see the other thread on Stolen Photos.
2. Her name and address only: unlikely, real scammers HAVE to use different names/addresses, if only to be eventually able to collect from Western Union or other sources.
3. Her photos, name and address : in other words, it's HER alright. In this case, her request should be posted alongside the scam report(s), so that readers can form their own opinion.
I do not know if anti-scam sites are amenable to setting themselves up as Courts of Law to adjudicate these cases. It reminds me of the situation of Criminal Law in my country. Up to some 10 years ago, we had the
procedimento indiziario (the Pubblico Ministero, our version of the District Attorney, would accuse someone of a crime based on some evidence, and it was up to the accused to prove his/her innocence), then we converted to the more Anglo-Saxon
procedimento accusatorio (innocent until proven guilty). Both systems have their pros and cons
