This one takes the cake, but let's start with the normal disclaimer about the legalities being a no-no on this board. This is mostly about jaw-dropping snowflakiness.
My brother has an unusual name, let's say it's Spiffy Spifferson. Spiffy is a pretty successful guy. He has a couple of businesses registered in his name, although he's never registered it as a domain name. He is very well known in his community. He recently purchased Very Desirable Car (VDC), a process that involved a lot of interaction with the VDC factory. He keeps meticulous notes, including several conversations with "Bob Boringname", an employee at VDC.
Well, sometime in the last few months, Bob Boringname left VDC to launch a brand of, let's say, special widgets for spiffy people. Remembering my brother's name, he went online and registered SpiffySpifferson.com. He then started a Kickstarter campaign to make and sell spiffy widgets. He even made a video saying the widgets are designed and made by Spiffy Spifferson.
Well, one of my brother's friends saw it and of course, called him and said, "Spiffy, I didn't know you're making widgets now!"
It didn't take much sleuthing for Spiffy to put two and two together. He contacted Bob, who admitted in an email that he took the name because he liked it. Spiffy very politely informed him that he couldn't use his name without his permission, but that if he was willing to give him some control over the widgets, he would not only allow him to use the name, but he would also sell them at one of the stores that he owns. Pretty good deal, right?
Bob's response: "I don't know, I'll think about it".
I'll give you two guesses as to what my brother's response was. And maybe a couple of days before SpiffySpifferson.com is no longer available.
