I am not part of the GB but have to say I found this statement extremely funny:
Not hard at all. Hundreds of people in on these group buys, only a couple of chuckleheads pulling out the pitchforks.

Being one of the chuckleheads, I didn't even bother to comment. I believe I've collected enough info for a small claims court filing vs. Mr. N...n (aka Ragingazn and a few more incarnations). I understand that supporting 3 relatives is hard for a middle-aged underemployed immigrant from a poor (but quickly developing) country. I'm sympathetic with that, I really am. But I refuse to sponsor scam. Besides, stealing hundreds of thousands of dollars is a pretty serious offense around where I live.
Currently, looking to confirm my info before filing a claim. If you have anything, please compare it with the 3 bits I gave above and if they match, we can compare it further.
