is hacking on the internet possible?
as you can see from the past, there are always ways ...
i am now checking one sponsor, as i think there are some hits missing, just waiting to get that kws into the serps and from pretty link on my wp it goes directly to sponsor campaign, so far there are missing hits, but waiting for higher volume. not sure if this is nats thing or what, but if someone click from pretty link it must count on the sponsor the same numbers
will keep you updated on this one
have luck
