Less Span in KO Approach Promo Emailing

We have now improved security on the KO Approach Promo Emailing section so that nonexistent e-mail addresses are no longer accepted.

KO Approach Promo Emailing is a service that enables visitors to get a KO Approach license for free. It is meant to let users spread the word about KO Approach through e-mails to their friends and colleagues. However, some people took advantage of a hole in our security and sent messages at nonexistent addresses. Well, not any more!

For a dedicated spammer it means they should now manually register at least ten fake addresses before a license can be redeemed. We would like to thank all the spammers for their great work at detecting this hole and thus helping us out. Thank you! Thank you! Thank you!
