Interesting. Nothing to do with statistics, but interesting.

No need for that.

The only way to *know* that is to get information from the sites.
If I wanted to be sure, I'd connect to them and look in their logs.
You probaly already know that people cheat a lot with this kind of
thing. Can't understand why they'd do that.

Is there a reason you're only selling - no, don't answer that.

There you go again. The only way to know is to go and look. But you
might try something along the lines of tcpdump on your firewall box,
so that you could at least remove a whole slew of uncertainties from
the equation. You could pull your magic numbers out from the packets
and see from the packet headers if they were addressed to where they
were suposed to be addressed to. But without going further afield I
think that's about the best you will be able to do.
And don't write off ab - remember, you saw it here first...
