I got surprised by my today's stats 52 clicks but only $0.06 something is definitely wrong with only 14-20 clicks daily but how it rises to 52 clicks ???
Get me traffic and continuously building it up and you wont notice such a drop in the amount of adsense clicks. Day to day stats can vary depending on a lot of factors, 30 clicks isn't a big difference if you look at the overall picture.
You should probably keep a close eye at your account, seems like a small click bombing attack, take care so that don't happen again in the future.
They will investigate whether or not the invalid clicks, violate their TOS. If you have nothing to fear, then, your in the clear.
I agree with an earlier poster, just shoot google an email letting them know of the situation and you are aware of it. You'll be fine as long as you did nothing wrong or your ad placement isnt against TOS
Man that really sucks - I actually saw a click taken away today. It was there one time I checked and the next time I checked stats it was gone!
