Found an interesting article a few years old about search engines and privacy.
One point that struck me as relevant was this:
"Many users do not understand why leakage of information not containing any
personal data such as email addresses or real names is considered
a threat by privacy concerned users. However the tiny bits of information
which get dropped every now and then form a trail which can be used
to trace users, i.e. the user is not anonymous any more but pseudonymous.
Being pseudonymous means that it is not known who the user really is, but it
is known that it is her. The problem is that giving personal data such as
an email address or a name only one time will make all past and future
pseudonymous actions personal actions which can be linked to the user's real
identity."

Just in case that might be any use to the more talented activists here.
