Social media management company HootSuite experienced over the weekend a technical issue that resulted in the leak of over 4,000 customer e-mail addresses to other customers. The issue took place on Nov. 10 as the company tech team was integrating Seesmic accounts with the ones already on the platform. Because of a technical failure in the process, new users were sent repeated notifications (read hundreds of) that contained other customers` addresses in the email headers. The gloomy part here is that disclosing other users` e-mails used with the service is always a bad idea.”]
