  text: 'Email communication is encumbered with a mass of email messages which their
    recipients have neither requested nor require. Even worse, the impacts of these
    messages are far from being simply an annoyance, as they also involve economic
    damage. This manuscript examines the resource ?email addresses?, which is vital
    for any potential bulk mailer and spammer. Both a methodology and a honeypot conceptualization
    for implementing an empirical analysis of the usage of email addresses placed
    on the Internet are proposed here. Their objective is to assess, on a quantitative
    basis, the extent of the current harassment and its development over time. This
    ?framework? is intended to be extensible to measuring the effectiveness of address-obscuring
    techniques. The implementation of a pilot honeypot is described, which led to
    key findings, some of them being: (1) Web placements attract more than two-thirds
    (70\%) of all honeypot spam emails, followed by newsgroup placements (28.6\%)
    and newsletter subscriptions (1.4\%), (2) the proportions of spam relating to
    the email addresses? top-level domain can be statistically assumed to be uniformly
    distributed, (3) More than 43\% of addresses on the web have been abused, whereas
    about 27\% was the case for addresses on newsgroups and only about 4\% was the
    case for addresses used for a newsletter subscription, (4) Regarding the development
    of email addresses? attractiveness for spammers over time, the service ?web sites?
    features a negative linear relationship, whereas the service ?Usenet? hows a negative
    exponential relationship. (5) Only 1.54\% of the spam emails showed an interrelation
    between the topic of the spam email and that of the location where the recipient?s
    address was placed, so that spammers are assumed to send their emails in a ?context
    insensitive? manner. The results of the empirical analysis motivate the need for
    the protection of email addresses through obscuration. We analyze this need by
    formulating requirements for address obscuring techniques and we reveal to which
    extent today?s most relevant approaches fulfill these requirements.'
