Their file creation dates differ.  However, they were last online within two minutes of eachother.

I've highlighted something I've found interesting - both posted their first pushup report within the same minute fourteen days apart.

They were both last active within five minutes of each-other.

VinsoN0's first post was just four days before ZeroVinsonN was spawned.

Conclusion:  Circumstantial evidence would suggest they are alts.
