'Black U' is a colloquial sales label, not a certification we can verify. These sources do not determine the status of any particular wallet; legal consequences depend on facts and jurisdiction.
USDT has issuer-level controls
Tether's December 2023 announcement introduced a voluntary freezing policy concerning OFAC-sanctioned addresses. A successful on-chain transfer is therefore different from an issuer guarantee that funds can never be restricted. It is also not evidence that every discounted offer involves illicit funds.
In June 2025, US authorities announced a seizure and civil forfeiture complaint concerning over $225.3 million in cryptocurrency allegedly connected to investment fraud. The announcement credits blockchain analysis and Tether's assistance. A complaint's allegations must not be presented as a final judgment against an unrelated seller.
Our takeaway: a seller's 'clean' screenshot or discount is no substitute for a credible counterparty and documented source of funds. Decline offers expressly marketed as criminal proceeds. Preserve transaction records and seek appropriate professional help if funds are disputed; another transfer does not establish legitimacy.
