A mail from the Adsense Team

A few weeks back I had mentioned about the useless traffic I was getting from the traffic exchange service -www.website-traffic.cc that someone had registered for. After returning from my break, I found a mail from the Adsense team who had detected the invalid clicks that had been generated on my Google Ads through users of the traffic exchange site.

This is what Adsense send me-

If we continue to detect invalid clicks or impressions from these services on your ads, we may disable your account to protect our advertisers.

Sincerely,

I replied back saying that I had nothing to do with this, but they have not responded so far. I wonder who directed this traffic to my site. I feel someone did it purposely because my friend Keith also got the same traffic and the same mail from Adsense
