Let the liking begin. No multis allowed. No limits of # of consecutive likes.
Useful tip - in lieu of the pre-emptive liking condition, you can guess the number of posts that are expected to follow you. If your guess is correct, you can like all the posts below you after the event (1). If your guess is incorrect, you will be disqualified. And the penalty would be a Cafe Interiview.
(1) Event - when someone posts after you, that is defined as an event. So each post after you is an event. Including your own posts that follow your previous post. (2)
(2) In other words, you get multiple chances to win this competition.
