His company was involved in a bribery scandal involving Zhou Jiangyong, one of China's biggest corruption scandals, "Ant Group" owned by Jack Ma was the primary beneficiary of the corruption done by Zhou. They've also been fined billions for various other financial crimes, including basically not complying with any financial regulations and scam loans to consumers, and it hasn't stopped them.
