Vietnamese Internet activist Nguyen Lan Thang posts a status on Facebook at a cafe in Hanoi November 27, 2013.

If you are reading this, there is every possibility that you have a Facebook profile. There is a further possibility that you have thousands of 'friends' to boast of. Let's admit that the so-called friends on Facebook are far different from your real ones. Now, you have got a chance to know if they really are your friends or they hate you despite being in your friend list.

Here comes www.hatewithfriends.com which gives you an opportunity to know who, in your friend list, hates you. When you go to the Web site, you have to log in with your Facebook user id and password. You must give it the permission to connect your Facebook account with the Hate with Friends Web site.

Thereafter, you will see a screen where you are going to find all your Facebook friends. There are two other tabs, one of which may interest you more. It is called 'Who Hates Me Too' which is placed just beside 'Who I Hate'. The process is really simple. In the 'Everyone' page, you will be asked to press 'Hate Him' or 'Hate Her' button placed just under individual profile pictures of your Facebook friends. The 'Him' and 'Her' is automatically selected by the Web site depending on the gender of your friend.

The Web site presumes that your friends too will visit the page and record whom they hate among their friend list. If they press the 'Hate' button for you, that will be recorded and shown in your 'Who Hates Me Too' tab. Similarly, when you click the 'Hate' button for a friend, it will be recorded. If the friend comes to the Web site to find out who hates her/him, you name will be visible. However, the trick is that your friend will not be aware that you hate her/him, until s/he hates you.

Interestingly, pressing the 'Hate' button is not an irreversible process. The moment you click the 'Hate' button for your friend, a 'Don't Hate' button appears that lets you reverse the hate process. You can also ask the Web site to notify you whenever someone hates you back by saving it in the 'Settings'.
