Gmail Now A Major Spam Hub

Moblog switches tack to create 'WordPress for mo-blogging'

When Gmail first launched, it was lauded for its spam filtering and security – there was no spam leaving the systems and almost no spam coming in. But all that has changed as a study from Roaring Penguin has found that spam originating from Gmail has risen from 6.8 to 27% in just the last month. The impetus for the big jump is likely to be that the Google account registration CAPTCHA has been completely defeated and almost doesn’t even stand in the way anymore.

We pronounced that CAPTCHA’s were dead some weeks ago, as there are now hundreds of thousands of ready-to-go accounts for Gmail, Hotmail and Yahoo now available to purchase online. With Gmail now responsible for 27% of spam, the trust mechanisms have completely broken down to the point where Google must take some drastic action to filter out automated users who are sending out bulk email.

They could do that by throttling the number of outbound emails, and some common sense user tracking. I don’t think any real user would be sending thousands of emails an hours, like most of the spamming scripts do – so it shouldn’t be too hard to detect and shutdown. Google have a big problem on their hands, and it will affect other Gmail users as the email coming out of the system is now being treated with increased suspicion by other mail handlers.

    Maybe ineffective CAPTCHA is the reason for Gmail’s seemingly perpetual beta label ;)

    But yeah, they seriously need to fix this.

    I don’t remember the name of the company that instead of checking out which users sends thousands of emails (a good spammer will always distribute sending and stay under the radar) but rather check to see if same identical mails were sent to many users (no matter the number of senders) at a specific time window – for google’s search and analysis capabilities this should be solvable issue isn’t it?

    Doesn’t Gmail limit the number of emails sent to 500 per day?
