Humm, yes, but I really don't like such functionalities - 
it can even "allows you to retrieve e-mail..", that is, 
leeching websites for mass-spamming. I know most offline 
browsers allow to leech emails/brute force URLs/use 
multiple proxies to avoid banning, but I don't think I'll 
ever implement one of these "features". I just think such 
features are made to abuse.
