Apparently the poor fellow posted the same kind of disingenuous sounding "this is a great book, oh, btw, I have one for sale" in multiple forums and elsewhere. His first attempt to sell the book (several weeks earlier) was before he had it in hand, so he found some other similar CGC book (same title but an issue # or two off) and used that scan in a sales thread hyping its rareness a bit (though it's a great looking 9.6 book).
Weeks later came the spam, and he used same kind of 'soft sell' tactics (highest grade available anywhere ever for sale or something).
Plus it's a pretty unforgiving kind of place, though he seems to have earned some flack because he's transparent but acts like he's innocent babe with only the best intentions for us.
