I read the news and it is true that the SinBad service has been seized by the FBI, Dutch and Finnish police.
And Sinbad was sanctioned by the US Treasury Department for North Korea's so-called Lazarus Group.
This article also mentions the signature campaign escrow address that still holds 0.35 and has received 15 BTC.
It is also said that the store is processing the mixed proceeds from the Horizon Bridge and Axie Infinity hacks.
