The investigation was led by CSA under the independent stewardship of former Constitutional Court Judge Bernard Ngoepe and supported throughout by the ICC Anti-Corruption Unit.
"I would like to commend my colleagues at Cricket South Africa for conducting such a thorough investigation and for working in partnership with the ICC Anti-Corruption Unit," ICC Chief Executive David Richardson said.
"Shared intelligence and cooperation is vital if we are to continue to drive corruption out of our sport. What is particularly satisfying to note is that it appears that any intended wrongdoing was disrupted before it happened, meaning the domestic games in question went ahead without any act of corruption being committed.
Richardson said both the intermediary and four of the players have accepted the sanctions and contributed significantly to the investigation.
"I would like to place on record my sincere thanks to those who reported their concerns to the cricketing authorities in the first instance and who were therefore the catalyst for the whole investigation. Without honest players doing the right thing our job would be even harder.
