Serious question: Some months ago I was curious about buying a domain name. So I poked around on various reseller sites to find out the pricing. I couldn't buy it at the time. Only a couple months later (I still couldn't buy the domain), I found the site had been registered. The domain was an obscure but novel sequence of letters; the likelihood that I and someone else came up with the sequence at the same time is objectively possible, but slim. So, I can only conclude that list reselling DEFINITELY DOES happen, and yes, I am very mad. But there is of course nothing that can be done. Now, when I want to find out what domains do and don't exist, I just use WHOIS, because I don't trust any of the "domain lookup" sites. What do I do now? :(
