I registered quarterbackclub.com back in 1998 & was going to do some fantasy football on it but never did.
Some lawyer sent me nasty letters telling me they held the trademark for it & said they were going to sue me for the domain ownership.
Never heard from them (or anyone else for that matter) again & I still own the domain.
I did own montgomerywards.com and they to sent me a nasty letter and the lawyer took a tone with me I didn't like so I sent him an email telling him to swallow my cock and pointed the domain to sears.com
The next day he changed his tone & he offered to buy it from me for some nice cash
