C++: StopForumSpam

17.05.2013 07:33 AncientDragon C++ 2 Comments

This is a complete console program compiled with Microsoft Visual Studio 2012 that demonstrates how to access the api from (SFS). The program sends a list of ip address to SFS and gets a reply that indicates which ones have been reported as spammers. The list of IP addresses is obtained from a tab deliminated file which was generated from a vBulletin forum web site. You can easily modify the program to get the list of ip address from some other stream.\r\n
