Just noticed and sent email to google with IP address. Adsense reports already show zero amount for 16 clicks. What else to do?
Try to use AdLogger (a PHP script) in your site: http://www.adlogger.org/ - this allows AdSense logging and you can set a max "user-can-click-my-ads" rate. I really like this tool. I've set a rate of max 5 clicks per IP/hour. Thats a little bit safeness. Informing Google is the right way.
i have also used adlogger and set range to 3 but i see 8-9 clicks from same ip sometime ,don't know what am i doing wrong
Yeah...better to be safe then sorry...send them an e-mail every time u see something wrong or that could be interpreted in a wrong way by them.
Yeah i'd reccomend AdLogger, and also to e-mail Google just letting them know of the situation. I assume using AdLogger is OK with Google? and you can use this as evidence to show them and let them know the precautions you're taking? Also would Google get suspicous if an IP was clicking once a day, every day? Can you set AdLogger to stop this say max 2 clicks a week or something?
