POST EDITED: Thanks to Shreevardhan, I have decided to remove this post as it encourages hacking. Personally I am fine with minor hacks which doesn’t harm anyone but this post was encouraging stealing of usernames. Extremely sorry for publishing it in first place and thanks to Shreevardhan and others for alerting me.
