I'm still struggling to find a reasonable argument in favor of wiping a user's entire history. Exactly three ideas come to mind:

1) Fur is concerned that the very existence of dual-boxing.com has been enabling his drinking. The constant pointless depressing niggling over reworking his UI to cut down on overhealing, or ensuring that Conflagration goes off as often as possible, has negatively impacted his recovery. On too many occasions has Fur woken up in an alleyway, always naked and often tattooed, croaking about /castsequences and how he hates getting vomit in his eyelashes. By written request of Fur and his sponsor, his contribution to the site has been wiped as a compassionate compromise.

2) The Latvian government is still on Fur's tracks after he blew town with a valise full of nuclear secrets and the Prime Minister's daughter. He gave the pursuing agents the slip all through Europe, only narrowly avoiding that explosion in France and an attack by bioengineered flying scorpions a few miles out from Gibraltar, eventually landing safely in the United States. His plan to relay detonator schematics back to his fiendish Quebecois employers by encoding them into d-b.com posts was a total success. Now the time has come to clean house and cover his tracks. Sufficient cooperation was secured when Fur revealed he had acquired photographic evidence of what Svpernova09 did in that petting zoo.

3) Drama!
