From paragraph 60 in the filing (emphasis is mine):
"As explained to OAG attorneys by Respondents' counsel. Bitfinex and Tether have also used a number of other third party payment processors to handle client withdrawal requests, including various companies owned by Bitfinex/Tether executives, as well as other 'friends' of Bitfinex - meaning, human being friends of Bitfinex employees that were willing to use their bank accounts to transfer money to Bitfinex clients who had requested withdrawals."
