Don't know where to post this so I tried here. Hope it's ok. I had thousands of visitors last couple of days. Analytics show that they are all direct hits, viewing average 3 pages and coming from different parts of the world, mainly usa, uk, eu countries, the visits I usually get. And they stick around for couple of minutes too. The only thing that is different then my usual users is the fact that they don't click on ads. Or trigger popunders. Are they bots? What is going on?
