I got an offer to try out SMARTDATE.COM through FACEBOOK but I was smart enough NOT to allow their app access to all my personal data on Facebook. Instead, just typed in their web address. I entered my photo and very basic info & IMMEDIATELY got responses. In fact, before I had typed anything about myself, I got a response back from a guy who thanked me for winking back at him - which I didn't do. He found my profile fascinating. I wrote him back that I didn't remember winking back & that I still didn't have anything in my profile information. I didn't hear back from him again. I just chalked that up to his error.
The thing that made me suspicious is that it seemed like everyone's writing style was identical. They even made the exact same mistakes in English: Namely using the word 'will' instead of 'would'. Conditional speaking is hard to get right, especially in English & it clued me in that they were not native English speakers. Men who listed themselves as Caucasian and living in London were consistently making very basic grammar errors. After reading a few of them, (before I even looked up the site for scams) I started thinking that they all seemed to sound the same. A lot of the men were from "Texas City, TX" which raised a red flag for me. Raise your hand if you've ever heard of it. Me neither. When I noticed that, I began looking at all their posts with speculation and deleting the ones that were obvious scams. After reading this, I'll delete them all and have Outlook send future emails from that site to the Trash bin.
