My speculation

Probably running the same modus operandi that they are related, as a married couple but claim to be 'divorced" since 2010 but continued to run the scam business by
- Getting victims to bank into TSH account but deal through Jessica.
- Upon scam being realised, blame to TSH whose name is already blacklisted by many ppl.
- Jessica claim innocence and move on to a more suitable time to repeat again, uses different number and probably another different ID.

Moral of the story is that, if it's too cheap, it's a scam.
