yep. You read it right. i am guessing the index page for my largest site was targeted by whatever was doing the invalid clicks. so every day there would be a huge reduction, which wasn't so bad because there was no revenue drop from previous months or year over year. at the end of the month the finalized earnings showed a 40% reduction. i replaced the 336x280 with media.net and the results were underwhelming. today i tried to put the adsense big box back on the home page and after two hours it still isn't showing. other adsense on the same page does show up.
