They use other methods of transferring cash than wire transfers
Simple methods
They long ago devised many ways to avoid taxes and launder cash and other assets and move huge amounts of money without being subject to government of international or domestic banking transfers ($10,000 US)
One was hiding messages or amounts of dates in graphics (silly & complicated & time consuming)
The simpler way is using the number of words in a paragraph (10 words - my first paragraph plus my second paragraph 2 words = 10/2 or $20,000 or an address #10 2nd Street or 5 to 9 digit zipcode or ?)
Or using every third word - or using numbers that relate to chapters &/or pages in a book or TV show on a certain channel
These are just a few ways of using similiar methods of coding or cyphering from many years past
An open post or a tagline on FR can hide a message to transfer $XX,000 of cash or money orders or traveler's checks to some name in Saudi Arabia or Bolivia or Kansas
In plain sight is the method most used - avoiding "keywords"
Emails and phone calls are too easily spotted and caught
