This is a great start-up idea, no? Your service shoots some kind of notifications (read, emails) to the owners of the accounts with poor passwords.
When you are sure your emails are read, you start appending ads to your notifications :)
Said notification will most likely go to spam or go unread, with a large percentage of the remainder causing misdirected anger at you for "hacking" their systems.
Even the most tech-savvy will probably be inclined to dismiss your notification as the ravings of some random script-kiddy.
well i did think about automating email notifications to warn users (but nothing ad-related though :). i'm not sure i wouldn't end up in the spam folder every time though!
I think a lot of users is and always will be clueless. Back in the days of dialup, with some ISPs it wasn't uncommon for those machines to be directly connected to the internet (rather than through a NATting router). It was AMAZING the stuff you could find by looking for (example) \users, or \documents.
