Two 'successes'
 
Did anyone else see two successes show up under xolotl's account for LL?

Yeah, right about now that user is submitting an average of a false prime every other day or so. 20 distinct machines of his have generated 216 total funky results (zero residue). Of the 216, there were 148 that reported as composite with a residue of zero, and an amazing 68 false positive "is prime!" results.

Those same funky machines, even when they're not spitting out zero-residue results, their results tend to be bad anyway.

On the other hand that user has a lot of verified results as well from other systems.
2822 unknown
2748 verified
204 bad
81 suspect

As long as the bulk of his work are turning in good double-checks and it's just a handful of horribly wrong machines, It's a net gain.
