I just don't understand what's in it for them. What's the point?
It's not really hurting my site per say, just messing up my stats. And as far as I can tell they get nothing out of it.
I am worried that it keeps escalating though.
Originally I was getting hit by around 20k a day. Then it stopped. Then it came back with 40k a day. Last week it peaked out at 66k.
