Not to discount you but back in 2016 I was buying my girlfriend underwear off the La Senza website since I saw their ads on facebook and I never knew they had physical locations, I always thought they were just a webstore.

Thanks for this. I didn't consider the online sales angle, but after doing some investigation it doesn't seem to change much my argument that "in all likelihood, the original poster was Canadian and therefore could NOT be "Mandy"."
To start with, this is what I was thinking when I wrote that. This is from the 2016 annual report of the then-owners of La Senza. At the end of 2016, nearly 97% of the physical stores operated by the brand in the U.S. and Canada were in Canada: there were only 4 physical stores in the United States. compared to 122 physical stores in Canada.
The report doesn't break down online sales and I'm not going to go searching for it, but it's pretty trivial to use Google Trends data for search requests for La Senza in 2016.

I am not 100% confident about the interpretation, I think the way Google Trends works is that the maximal result in each category is indexed as 100 and other results are scaled proportionally to reflect that. If that is right, then adjusting for the population difference, this implies that the US would comprise roughly 9.1% of search traffic in the US+Canada at that time. This would not include things like Facebook direct advertising though.
It doesn't really matter as the pictures are obviously stolen. If they weren't there would be no need to alter them so severely and pretend they were just taken now.
If I remember correctly, that's exactly what Mandy did. He/she claimed they were taken nearly a decade ago. But based on his/her story, it was realized that if this was true, the pictures would've been taken while she was in high school.
People said this, but it didn't make any sense, because if "Mandy" was born in 1989, "she" would have graduated high school around 2007.
It doesn't matter though, because the photos are stolen and Mandy doesn't exist.
Also to add I don't know why they felt the retarded need to convert their fake pics to fucking 400px gifs like this is 2000s texting, as far as I remember, though Google might be better now, you can simply defeat reverse image search simply by rotating the image 2 or 3 degrees, cropping, adding noise and maybe down scaling like 50%
They did all of that: rotating, cropping, flipping, adding noise, converting to GIFs, and it still wasn't good enough.
