I stumbled upon a not-so-recent
article at the Channel 4 News Investigation website. It's about one of Britain's biggest internet dating companies, Global Personals, having scammed its members with countless fake profiles called "pseudos" and making them pay more than the registration fee.
I can't embed the video on this page but fortunately, the producers uploaded the same video in Youtube.
It looks like Global Personals runs a White Label Dating site. This makes me wonder if there are still honest dating companies nowadays who operate with a little integrity.
