Spammers harvesting emails from Twitter - in real time
Spammers are no strangers to the ever-growing Twitter. From commercial Twitter spamming tools, to re-tweeting trending topics for delivering their message, a new crafty search technique can provide spammers with fresh and valid emails harvested from Twitter's users in real-time.
Basically, the search query consists of common phrases such as "email me at" and "contact me at" in a combination with a domain of a spammer's choice.
The result? A flood of valid and fresh email addresses of Twitter users unaware that their emails will not only get indexed by public search engines, but also, that the output can be syndicated for spamming purposes.
From theory into practice - a day after the tactic was discussed a proof of concept script was released, even though it should be logical to assume that the practice has been taking place for a while now.
You are solely responsible for your conduct and any data, text, information, screen names, graphics, photos, profiles, audio and video clips, links ("Content") that you submit, post, and display on the Twitter.com service
And whereas that should be the case, what Twitter can do to at least slow down this efficient email harvesting approach, is to either allow its users to choose whether or not they would like to have their emails/phone numbers obfuscated (reCAPTCHA Mailhide), or enforce the policy to all users.
