This is not the case IMO at it costs 5 credits and is easily offset by the extra PG views it will generate, similarly to display a phone number is 1 credit and they both add authenticity. This profile does not display a phone number, she doesn't treat emails properly yet the Gallery is 2 credits. Looking at the photos my view is scam. I see she is in Northampton, Derby, Burton, Nottingham which is a wide area and why wouldn't Leicester be listed, any idea how long that's been the displayed area?
No idea Jacob, I'd hazard a guess at about 3 weeks or so. You say it costs 5 credits to display available today. Do you know how long this buys, a day, a week?
You make a good point though. This can be a nice little earner. Consider, she's had (at my last look) 12,500 views. Now I don't know how many PG subscribers you can typically expect but let's say she gets just 2%, that's 250 subscribers at £2 each giving £500. It could be easily ten times that though.
On top of that, her face does not show in the PG so these may not even be genuine pics. I have TinEyed them without anything showing as suspicious but that is not 100% it just tells me they are not on TinEye.
