Double jeopardy protection is for criminal charges, not civil.

Apparently double jeopardy doesn't apply in two different states, regardless of the type of charges. Which fits my limited expectations around it - it prevents a single court system from attempting multiple times on the same case... A second US State would have no restrictions against them.

Yeah, but wouldn't it really be a different crime anyway? I mean, state A would charge you for ripping off people in state A, state B would charge you for ripping people off in state B. Two, presumably disjoint, sets of people.

This ruling is only for backers in Washington so that appears to be exactly the case; other states and countries can still file their own lawsuits if motivated to do so.

It would appear this ruling and the accompanying restitution is only for the backers in Washington state. Each state could in theory pursue its own lawsuit for its own residents.
