Unless they're the crew running girls through Catford, Balham, Wood Green and Cambridge who send real pics via WhatsApp OR the SP is a recently reviewed girl confirmed genuine then the certainty for Chinese/Japanese/Korean/Singapore/Malaysian/Taiwan advertised girls using patently fake pics is that it will be a B&S; either for an old crone who may be free to work or a youngster with no English (likely not a student) and more likely to be trafficked/coerced.
There may be other Chinese crews being honest about who's working but I don't recall. Other UKPers pls chip in by starting or adding to a London Region thread about Genuine Chinese SPs in AW/VS/etc.
