Hi Jan,
about the Google bot you can easily exclude using parameters in configuration.
I've also tested the list of IP you sent me on this web service
http://www.hostip.info, and it seems that location can't be found:
27.111.50.174 US must be ID
36.68.7.252 US must be ID
36.68.18.207 US must be ID
36.70.97.63 US must be ID
36.73.40.230 ID correct
36.73.231.99 US must be ID
36.73.104.116 ID
36.74.209.246 ID
36.80.226.28 US must be ID
36.81.138.57 empty country
36.85.102.152 US
......
Any ideas? Maybe some issue due to IP in Indonesia?
Thx
John
