It sounds like Jeffery hired someone smart to handle this for him and didn't buy SA LLC, only bought its assets. This both introduces an additional step in Doxxing him, and keeps the myriad of people Lowtax stiffed from being able to legally come after Jeffery - it also keeps Jeffery from having to settle out the lease on a GTR bought by a crumbling-spined loser who bought it based on advice from his bi-polar live-in mormon coke whore/business partner.
It is very likely that Lowtax negotiated himself a slot as a silent minority in Jeffo's new company. Because as much of a druggie as Lowtax is, I can't see him just completely abandoning his sole non-mommy income stream for over the past two decades.
Its also possible Lowtax structured the deal as something like "Enough money to pay off taxes now, and then a % of revenue in the future"
But as
@Spunt mentions above, we might be giving Lowax too much credit. He might have just seen a 6-figure offer and decided that could buy a lot of ambien.
