I've been thinking, and what's stopping someone from clicking your ads over and over to get you banned? Also, what's stopping them from taking your ad code from viewing your source and using it on a porn site or something?
With your first comment - click bombing can be stopped with a program that I can't remember the name of >.< And with your second, nothing really - if you notice that something like that is happening then you should tell Google straight away and I guess they'll do their best to sort it out.
Oh My GOD, never thought of the second question. Guys what's the solution for this??? Concerning ur first question: use adlogger: http://www.adlogger.org/
even if you can protect your AdSense ID, someone could use a simple program to get you banned. read this: "Abbas Manjothi: I make one software 2 put impressions on ur site Abbas Manjothi: ... amit patel: ... amit patel: ...? Abbas Manjothi: it refresh sur site after 15 second Abbas Manjothi: .. Abbas Manjothi: I just open that site by software then it automatically put impressions amit patel: .. amit patel: .. Abbas Manjothi: ? Abbas Manjothi: I make it nothing else yaar amit patel: oh gr8 Abbas Manjothi: Well if i want 2 bann u then i can but i am not tat type amit patel: ok amit patel: but why will u try to ban me? Abbas Manjothi: I have already banned 10 persons By simple software " taken from this post: http://forums.digitalpoint.com/showthread.php?t=76919&page=2
Yea, it isi really quite ridiculious to prevent somebody from doing something unwise, what you can do is to have a good AdSense tracker and report any suspicious activities to the AdSense Team immediately.
