I cannot ever recall seeing this profile in the East Mids section before.
In addition, although the FB is Zero, it is hidden. For someone who's had a profile for over 20 months, I would have expected some feedback, esp from those who may have got frustrated and left a comment to say that mobile not answered/emails not replied, etc.
At worst, I would ignore profile, at best put it in your HL and make as much notes as possible, as to her profile name / location/ mob number/ no of pics in PG, etc to see if you notice anything untoward, e.g. keep changing locations regularly.
