"you have been reported, you must announce changes to income to the settings"
It may be the polite thing to do but it is by no means required. It is up to the person joining the game to review the settings prior to joining. The onus is entirely upon you.http://wiki.warlight.net/index.php/Cheaters
Check the game settings
Sometimes sneaky players will change a game setting and hope that their opponents don't notice, then try to take advantage of that setting change.
 Overridden bonuses
Game creators can change the value of bonuses, and someone could set a bonus to be much bigger than it is usually worth. Then they attempt to capture that bonus at the start of the game, giving them an easy victory. In these games, be sure and check the settings yourself and deploy there yourself to prevent your opponents from capturing that bonus.
Rather sad that someone who has been around since beta doesn't understand the simple concept of checking settings before joining an open game...
