Probably in the same way it prevents Megas XLR from being revived or released in any form:

> So here’s the ugly truth from what I understand, and I’m neither a lawyer or accountant so my understanding could be off – Megas was written off as a tax loss and as such can not be exploited, at least domestically, in any way, or the network will get into some sort of tax/legal trouble.
From looking at the wikipedia definition of "write-off":
https://en.wikipedia.org/wiki/Write-off#Accounting
> In business accounting, the term 'write-off' is used to refer to an investment (such as a purchase of sellable goods) for which a return on the investment is now impossible or unlikely. The item's potential return is thus canceled and removed from ('written off') the business's balance sheet.
So if a "write-off" is declaring it impossible to get any ROI on investment and you then get some return on it (after e.g. reviving the show, selling DVDs of it, etc), you've lied to the federal government to reduce your tax burden.
