There is a rule of no ISO begging on the Saturn and Sega CD forums. Usually someone begging for an ISO is given a chance, but repeat offenders may be banned.
There is a rule that state you may not even speak about copied Dreamcast games, lest you be banned.
Are you getting the drift?
There seems to be an unspoken warez ban, although that doesn't seem to cover CD burning or FTP client software.
However, the FTP forum is meant to be a resource for server details and giving feedback to FTP admins.
ISO begging is... discouraged, and finding things out for oneself is encouraged.
Not that either are necessarily adhered to.
