Hi,
when i generate a userlist with filtered any users it is able to modify the url with the username of another user who is not listed in this list load him also with this url. So google can crawl this to.
For example:
userlist1:
url:http://www.mysite.com/usergroup1/userprofile/user1
the same user ist not listed in userlist2
url:http://www.mysite.com/usergroup2/userprofile/user1 <---- by change it will listed also
why? And how can i fix it?
