Twitter users have been a victim of several DM scams and phishing scams in recent times, most of the times, users were send scam links, clicking on which would ask users to enter twitter details or compromise a user’s account, and then send out similar messages to their friend list.
However, that may be a thing of the past, since Twitter will now pass all the links in Direct messages through one of their own services, so that they can track and halt the problem at the core itself.
What this means is that if someone sends you a link in a Direct message or if you receive an email with the direct message, the links contained in them will go through twt.tl before reaching the destination URL.
This is definitely a smart move, considering that Twitter can disable a user from visiting a scam or phishing URL at their end itself. This will also allow Twitter to quickly avoid a scam from spreading across to multiple users.
I was always wondering on how Twitter would take steps to stop the DM scam, and this is one of the best possible solution one could come up with. Way to go Twitter, this is brilliant. More info at the Official Twitter blog.
