Clicking the ads multiple times in a day by the same person will cause PS to be banned by google ads program. They check for "fake" clicks, to ensure the program is useful to the companies that pay for advertizing. Thanks anyway for your support. I appreciate the fact you wanted to act in favor of PS, that's much appreciated. In addition, as part of the program, PS team is not allowed in any way to incentive ads clicking, and so we will not.
So please DO NOT click repeatedly the ads.
Crap 
Just FYI:
AdSense uses quite a lot of mechanisms to track clicks and to prevent click fraud. The obvious two are Cookies and IP addresses (I wouldn't be surprised, if they used browser fingerprinting as well). If you think now that clearing your cookies and cutting your internet connection between each click would do the trick, think again. The third big mechanism (that cannot be betrayed) to prevent click fraud is a web bug on the advertizers "thank you for your purchase page". That is, if AdSense sees a large number of banner clicks, out of which none ever makes it through a purchase, they can pretty much suspect that click fraud is going on and given the fact that there is no shortage in aspiring publishers, they can pretty much afford to kick/ban on the basis of a suspicion alone (yes, the contract, you sign as a publisher explicitly gives them the right to terminate it on whatever reason).
I would also like to note that banners are not mobs that need to be clicked to death and looted afterwards. Advertisers don't pay publishers for getting people to click on their ads (that would be completely pointless!). They pay for the referral. The goal of every banner is to produce some kind of sale out of which the click is payed.
In other words: if you want to PS to earn an honest buck, you'd have to buy something after clicking a banner. But then again, in that case you could also directly make a donation via paypal or whatever and give the PS team the full sum instead of the breadcrumbs, an advertiser would pay for a lead.
Having said all that. Good luck with AdSense on the forums, Talad. I doubt though, that it will turn into a viable source of income. The PlaneShift community has taken every attempt of inbreeding in the last couple of years ("if you don't wanna roleplay, go play somewhere else"). This is especially true for the forum which only has a couple of frequent posters/readers. You can only make money from AdSense when you have literally thousands of page impressions coming from thousands of different people (remember: each click ideally leads to a purchase. How much stuff can the few hundred PS Players possibly want to buy?).
Well, maybe that will finally lead to the insight that the "PS is only for elite roleplayers" point of view is futile ... Then again ... who am I kidding?
PS: Maybe you want to look into "project wonderful" instead of AdSense for the beginning. Their payout is crap, but unlike AdSense/Adwords you can use your earnings directly for advertizing yourself on other websites without fear of click fraud, as banners do not earn money per click but per time. Webcomics seem to make heavy use of it to shift around their readers, so I guess, while you don't make a lot of money out of it, it can at least be good for community building.
