factored exponents assigned

I saw some huge "bits factored to" exponents in the status.txt file of 2007-05-17 08:00 :

Code:

All those exponents have known factors ! Even more curious : 28433389 was assigned a few hours ago. The factor found is not recent (it is not the cleared exponents file.)

Looks like somebody manually factored it using FactorOverride option (look at those high bits!) and reported it to PrimeNet, thereby tricking the server to add it to the "To be LL-ed" queue.

Any better explanations?

If the number is factored it does not need to be LLed. The factors probably comes from the P-1 stage. Anyway those four exponents do not need to be LLed and should be removed from the users worktodo...
