I have a question regarding the number of unique visitors per value of our ClientID prop.
I have this prop, let's call it prop42, that is equal to our anonymized ID number for each client.
When I see the results of this prop regarding the Visitors, I get many prop42 items that have a hundreds of Visitors ( even for a one day analysis ).
How is this possible ? Are these clientIDs from malignant users ? In theory they should erase their cookies in order to be counted as a new visitor, then log again to our site with their login and password ?
