Also on the upside, Hobby Lobby got swindled from fake Dead Sea Scroll excerpts.

Got swindled from? Ok, so some fake Dead Sea Scroll excerpts had this Hobby Lobby thing and somehow the Hobby Lobby thing got swindled from them (them being the fake Dead Sea Scroll excerpts)?

Got swindled over some fake DSS excerpts?
Got swindled by some fake DSS excerpts might work seeing as it was their fakeness that enabled the swindling, but even so I’d expect the swindling to be attrributed to a person - a swindler, who does the swindling.
