I don’t want to go in details and risk my own blog. So basically one of the scripts that’s very common among websites is targeted and redirection code was injected.
Using Adblock, you can simply block this script:
http://platform.twitter.com/widgets.js
And then you won’t get redirected. It’s that simple. 🙂
There might be other scripts I haven’t encounter yet, but you should be able to use the same technique to block them as well.
