Many FTPs advertised as "new" are actually dead. You pay for access, only to find the server has been offline for months.
Hackers know that programs run on the FTP pass through hundreds of USB drives. It is common for a "new version" of a program to contain a keylogger designed to steal Transfermóvil banking codes.
Are these "Programas New" legal? Usually not. But they are necessary. Until Cuba sees affordable, high-speed fiber to every home, the FTP server will remain the king of the island.
