There's a Twitter virus going around - all afternoon my feed has been full of people repeating the following message.
Don't click, it teases. And of course people do. It's not worth it, honest.
I couldn't resist either but I set up a test account to see what would happen. I took some screengrabs for reference and to save other people the hassle.
When you click on the link - http://tinyurl.com/amgzs6 - you're taken to a simple web page with a button that looks like this.
At the bottom of the page, there's a single link to Korben.info.
(If you want a screengrab of the page in full then you can find one here.)
If you press the button at the top of the page, nothing obvious happens - there's no response. But the next time you look at Twitter, you've updated with the "don't click" message.
And that's that. Boring. So now you know - don't click.
There's a proper explanation of how this works here.
