I left bad feedback (revealing the scammer) on the site and emailed the site admin and received an email the next day that the user and their ip has been banned, the "site" may actually be a decent place to do business, but "emily" sure wasn't a legit trader...
I may give it another shot, and just be more careful next time...
I'm really sad that someone has used my website to scam people. I implemented the feedback system to help prevent this in the future, and I've created a system for admins to keep an eye on suspicious users. This system checks various things such as feedback posted by the same IP address, and other things. I also added some tips about trading using Bitcoins.
If anyone has tips to help making my website better, I always like to hear about it! You can contact me here or using the contact form on the website.
