Anyone else noticing a significant drop in clicks lately?

Not only have the clicks dropped, but the ppc has dropped harshly, categories in the dollars are now down to pennies.

Also, regularly, only earnings producing pages are listed with daily reports but now some pages are listed showing '0' clicks, among these, are some with one or two cents. Realizing that balances are sometimes corrected the next day I've looked back, but the '0' click pages stay the same.

Is this more than the end of the month syndrome?
