Here, this might help.
Run this SQL query
C#/VB.NET Code:
SELECT
CreatedOn,
LastIPAddress,
Referrer
FROM
Customer WITH (NOLOCK)
WHERE
Email = ''
AND CreatedOn > dateadd(dy, -7, getdate())
ORDER BY
CustomerID DESC
It will show when the anon customer was created (something was added to the basket thus they are added as an anon customer), the last IP address - use this to check against on the honey pot project (if you see the same IP multiple times) and the referrer - so where they came from, spam bots etc. do not normally have referrers.
It will get the information from the customer table where they have a blank email (thus an anon customer) and they were created within 7 days ago (change the value from -7 for less days i.e. -3 for today and two days back.)
Finally it will order them from the latest to the oldest.
From here you will get a clearer indication of what is going on with your anon customers.
Hope it helps out!
