I stumbled onto this site. I had to create an account to contact sellers. No responses. Did a google search and found people were calling it a scam site 6 months ago.

I don't know what these sites scam actually is. Perhaps they are looking for email addresses and passwords. Thankfully I used a unique password that I do not use anywhere else. If they contact me, I think I will waste as much of their time as I possibly can. I would love a face to face meeting, but that would never happen.
