Pretty sure this expired ad from about 1-1/2 to 2 yrs ago for a Lost World backglass was posted here on Pinside by a scammer.
I see that the ad got re-listed twice.

At the time asoccer7 was a new account here on Pinside with only 1 forum post (and none since), so I knew to proceed cautiously.
He contacted me first by sending me a PM asking if I still needed a backglass (because I was looking for one).
The back and forth msgs & emails were going fine until I asked for a current picture of the back-side of the bg.
Don't recall if I asked him to be in the pic holding the bg or with a handwritten note by the bg showing current date, or something like that. Communication stopped after that. Never could get him to answer the phone to the number he gave me.
So, I was bummed that I wasn't going to be getting a backglass, but happy that at least I didn't lose any money.
May or may not have been a scam, and I never did a search online to see if I could find those same backglass pics elsewhere.
Several months later I sent ForceFlow a PM telling him about this and asking to at least keep an eye on asoccer7.
He let the other moderators know about this and replied to me. The account is in an "inactive member" status, and probably has been for about a year or so.
Welp, that's my little story to share. Sorry to hear that the OP got scammed, but thank you for sharing your story. Glad it was not a huge amount of money.
