My CTR was avg. 0.85%. The better viewed site had 20000 pgv a day and the earnings were roughly 15-18$ a day. The email I got was redirecting me to Google's AdSense help page on invalid clicks. I kept the same or very similar stats for the last 7 months. I have never clicked on my Ads. The color on the ads was black and white compared to the background so in no way it was deceiving. The only thing comes to my mind is my competition suddenly bot clicking or something. They were both in the same niche but very different in nature. I know I said earlier irrelevant in nature but the way they engage their targeted audience. NO spam, no scraped content no link building for the last 1 year.

P.S. I do have the same whois info on both domain. And I do run some affiliate offers too.
