I get irate when I search for "PCGS" and a bunch of ungraded, unslabbed coins pop up. One seller was particularly egregious. I reported about 15 of his auctions (yeah, yeah, I know, I wasted a log of time but it was the principle). The coins didn't sell and the seller posted them again as PCGS coins, so I did it again. A few days later I noticed none of his coins popped up when I did the search. Before reporting the auctions, I sent this guy a private message and he rudely sent me a reply saying "I don't see no (sic) PCGS nowhere (sic)!" I gave him a chance to do the right thing and he played dumb. So maybe they do listen.
