==== NAME ==== Posy::Plugin::AntiSpambot - Posy plugin to obfustcate mail links. ==== VERSION ==== This describes version ``0.50'' of Posy::Plugin::AntiSpambot. ==== DESCRIPTION ==== The aim of this plugin is to frustrate the attempts of spambots to harvest email addresses from your website, by concealing them by altering mailto: links according to a given policy. The choice of concealment policy is up to you. Policies: spell Convert the link to plain text where the email is spelled out; the @ sign is converted to ' at ' and the '.' parts are converted to ' dot '. cgi_link Convert the mailto link to a link to the Posy cgi script with two parameters -- the username and the domain of the original email address. When someone clicks on the link, AntiSpambot will then interpret these parameters correctly and display a special page which contains the original mailto: link. Because the spambot didn't know that the cgi_link was for email, it doesn't harvest the email address from the cgi link, and the user is only slightly inconvenienced. form This is just like cgi_link above, but instead of putting the parameters into a link (which might be parsed by the spambot) it puts it into a form (which spambots are less likely to parse). And you get a button for folks to click on. == Activation == Add the plugin to the plugin list. This plugin creates an 'anti_spambot_obscure_mail' entry action, which should be placed after 'parse_entry' in the entry_action list. If you are using the Posy::Plugin::ShortBody plugin, this should be placed after 'short_body' in the entry_action list, not before it. This plugin also creates an 'anti_spambot_show_mail' action which will check the incoming parameters and display a special page with a mailto: link. It needs to be placed after set_config in the action list, as it checks config variables. == Configuration == This expects configuration settings in the $self->{config} hash, which, in the default Posy setup, can be defined in the main "config" file in the config directory. ``anti_spambot_policy'' The policy to use on email links. By setting different configs in different directories, you can change this on a per-directory basis. ``anti_spambot_at'' The string to replace the '@' sign with if using the 'spell' policy. (default: ' at ') ``anti_spambot_dot'' The string to replace the '.' with if using the 'spell' policy. (default: ' dot ') ``anti_spambot_prefix'' The string to prefix the email with if using the 'spell' policy. (default: <) ``anti_spambot_suffix'' The string to append to the email if using the 'spell' policy. (default: >) ``anti_spambot_user_param'' The name of the parameter to define the user if using the 'cgi_link' or 'form' policy. There is deliberately no default for this, because everyone ought to define their own parameter, so that the spambots can't figure out a pattern. ``anti_spambot_domain_param'' The name of the parameter to define the domain if using the 'cgi_link' or 'form' policy. There is deliberately no default for this, because everyone ought to define their own parameter, so that the spambots can't figure out a pattern. ``anti_spambot_message'' A message to put on the special page which displays the mailto: link when using the 'cgi_link' or 'form' policy. (default: '

Sorry for the extra click, but this prevents email harvesting.
