I came back to collecting last May 2016, and found this board.
From my last active ebay days, during 2007-2008, there were two personalities that stood out, one guy bought nearly every copy of IMSM1 (C.C.), and the other had the angry man listings that lasted two pages (silver age marvel comics only 1).
So of course, now I know more about who was behind the calamerica collectibles purchase of every available IMSM1. What a character, but then, that could be said about half of us in some context.
And last year I took a small gamble on a minor book from samco1, whom I already figured out for myself grossly overgraded.
Turns out I was still blocked from nearly 10 years ago. Talk about lucky ! Can't recall what kind of note I sent to him back in 2008 that led to my being blocked.
[Actually, I also remember Showcase NE for those broken-out run listings (1, 2, 3-5, 6- 10, etc.), overgraded only one or two grades mainly in terms of abuse of the meaning of "average" grades. But mostly it's the negatives I remember, and SNE was among the better ones in those days.]
