Hi, Dirk

this new rules.....

QRZ Callsign Database Policy Change
  Effective today, the QRZ Callsign database is changing the way we serve 
callsign data to our web (browser) based users. These changes have been 
brought on by a steadily increasing number of automated systems that access 
the QRZ data in so-called hidden or stealth mode. Such systems create a 
significant load on the QRZ servers and in doing so, deprive ordinary users 
of the performance that they deserve.

  These robots (or 'bots') come in many forms. Some are designed to scrape 
the entire website for every piece of information we have. Others, known as 
"log checkers" are programs written by hams that repeatedly query the QRZ 
servers while working through lists of 10's of thousands of callsigns, doing 
it as rapidly as possible. Finally, some logging programs provide "auto 
fill" features that use the QRZ servers in the background to fetch callsign 
data as soon as the user types in a callsign.

  For the past several years, QRZ has provided an XML Data service that was 
specifically designed to serve automated requests such as those described 
above. The XML service is an extremely lightweight and flexible system that 
places less than 1/10 of the load on our database that a "stealth" callsign 
lookup does on our regular pages. In addition, our advertisers are being 
deprived of ad exposures by these programs which routinely ignore or discard 
all such non-callsign data as they scrape our site.

  Today's changes address these issues with a new set of constraints that we 
have developed with the goal of providing fast and fair access to all QRZ 
users. The following is a summary of what these measures mean:

    a.. Callsign data, including name, address, and other QSL and logging 
information will be shown only to registered users of QRZ who are logged in 
at the time of the request. Guests that have not logged in will still see 
the callsign Bio page and pictures, but no callsign information will be 
shown.
    b.. Registered users who are logged in will see the full detail on 
callsign pages.
    c.. Ham users, i.e. those whose user name matches a callsign in our 
database, are limited to 150 callsign page lookups per day, not including 
their own callsign page.
    d.. Non-ham users, i.e. users who aren't hams or don't have a username 
that matches one of our callsigns, will be limited to 25 callsign lookups 
per day.
    e.. QRZ subscribers, of any type, are granted unlimited daily access to 
the QRZ callsign data.

  These limits are designed for fairness and the vast majority of our ham 
users will never be affected by them, aside from the new requirement that 
you must be logged in to see callsign data. Note as well that when looking 
up or viewing your own callsign page that the act does not count against 
your daily lookup limit.

  We ask for your support in accepting these changes and understanding that 
they were necessary in order to maintain the high level of service and 
support that our users have grown accustomed to.
