I've never seen this before - I received several clicks early this morning but earned no revenue. Has this every happened to anyone? Is it possible the clicks were on Google's own ads which they don't pay for?
My guess is that you just need to give it some time. I've seem similar things in both Adwords and Adsense. For example, at times the click thru rate for some terms in Adwords exceeds 100%. I think the data is drawn from multiple sources and the timing does not always match up. I generally wait until the next day before considering it reliable.
it has been heard of people clicking their competitors - google should refund your fraudulent clicks (same IP several times...). Check that regularly to be on the safe side...
Kind regards!
