How to get some likes on facebook?

[BlackRipper]

I entered a manga contest on facebook, I uploaded my drawing and now all I need is some likes. I don't want to win the first place, I just want to be among the first 10 (as there are 10 prizes). But almost all my friends on facebook are a**holes.... Out of 140 friends, I have only 9 likes (and 3 of them are from myself (( ). So, what should I do to get more likes??? Any advice?
for abraxus, it's a contest organized by facebook, not by any other site....
it's just that the prizes are provided by wacoom. and you don't go on any other site to vote, the voting ALSO takes place on facebook(so it's not spam )

people these days wont like your stuff just so you get to win a prize... the people who do that get spammed... do you even understand how all of this works? "contest sites" are a scam to get people to advertise their page for free... people are sick of that - it's spam to them
