>If the accuracy of the profiles decrease, it is discovered.
We do not know the algorithms. I doubt, they are able to filter items which
are bought
in the name of a proxy person. I do not say, people should not act as a proxy
person,
but they should know what effects it may have.
>you expect a solution where, at once, all profiling techniques become
obsolete
I do not expect one.
>you have such a solution
No, I do not. My post was about showing, that gnutaler cannot work as a tool
against profiling.
And if gnutaler does not provide a purchase protection system, people often
will have a
reason to not use gnutaler. I am in favor of gnutaler, but I think gnutaler
should provide a purchase protection too.
