Im going to guess that's not even her picture
Why is that your guess? Punters on this site and in this thread have confirmed that this is the girl they saw. The picture has not changed, but the person behind the account may have.
As already mentioned, for those intent on disbelieving that a young mixed race girl could be involved in such a thing, the only scenario that takes her out of picture is the unlikely event that the profile was sold along with her pics - even then, what scammer would pay for an AW profile with just 2 reviews on it, when they can create one for free and fabricate the reviews. The second scenario is that she's in debt and has let some nasty types have access to her profile - this scenario also makes her guilty, as she'll know what their intentions are. Even then, there would be no need to use her own pictures, as such a scam could be carried out with any profile and any picture. The most likely scenario is that a) she knows what is going on and b) is a willing participant in the event
The conclusion? The girl is at fault and allowed her pictures and account to be associated with this.
