Quoted from JodyG:
What is his legal basis for demanding his scores be added back to the Twin Galaxies listing? They are a private company and can allow/exclude whoever they want.
I don't see a legal basis to require Twin Galaxies to add Billy back into their listings. Billy's letter says that if they don't add him back in, he'll sue them for defamation. No idea if he's got a legal claim against Twin Galaxies. So far as I can tell, their statement was just that they caught him cheating at DK once. Unless he can prove that they knew or should have known he wasn't cheating but said it anyway, he's probably hosed. From a quick skim through his amateur evidence package (note to self, always start legal brief with booth girl pics), I don't see that happening.
Billy might have a claim against Guinness for implying that his unchallenged records "NEVER WERE," though their wording is careful and vague enough that they're probably OK. But even if he won that lawsuit, he's not going to get a court order requiring Guinness to identify him as the record holder going forward.
I understand Billy's overall beef -- by all accounts he legitimately set a bunch of records, and it seems a little weird to say that some other guy was the first person to "beat" Pacman when there's no reason to think that particular score was a cheat. But Twin Galaxies gets to set their own policies, and if it's "one strike and we erase you from history entirely" then so be it. And Guinness can rely on whatever sources they want to prove up the "world records" they chose to publish, even if that means they ignore a bunch of seemingly legit records in the process.
