Here's my quandary. I set up at local shows, and there's a guy who travels all around to various cons as a buyer. I always had the idea that he was a reseller, which is fine by me. I have a price on my books and if you think you can make a profit on it, I have no problem selling to you. However...
I am a member of various Facebook groups where people sell comics, and I noticed that he sells there. The only reason I was able to connect the dots was when he put up three things that I sold the at a show the previous day, all of which were odd enough that it had to be him. While some of his sales on Facebook are a straight price for comics, about half of them are raffles. He will sell 10 or 15 or 20 spots for a specific price and then have an automatic number generator pick a winner. He ends up collecting around twice the value of the book from these poor suckers who are trying to win.
For example, he had a New Teen Titans #44 CGC 9.4, selling 15 spots at $10 each. He gets $150 (minus Paypal fees). You can find this same book on eBay for about $75.
Now, I'm not going to tell someone that they're being idiotic in trying to win these comics (even though it's obviously not worth it), and I'm not even going to tell this guy to stop doing it (even though it's against eBay's policy). But I do want to tell him that I'm not going to sell him my stuff. Am I being overly sensitive? Should I just not care? He's not buying anything that I couldn't sell to another person.
