I finally found how to unlock this.
you set 8 players and 3 audiences.
Play as Player 1.
Because you cannot get LIKEs when your drawing is shown, You have 7 chances to get LIKEs.
if you set 8 players and 3 audiences, you can get 10 LIKEs each drawing.
Player1 answers "fake", so others must select "fake" at AWARD LIKE select.
Be careful, audience also have 2 choice with answer and award.
And you should not be paused the game when you are voting.You have to operate quickly.
and TOXICCOOKER saids at comments,please watch his comment.
"This achievement is actually possible with 6 players and 1 audience member"
and lfcjohn saids at comments,"achievement pop immediately and I quit afterward".

And when you got this achievement, you can get "Wait, Why Are We Rewarding This?" at next round.
All of players don't input the answers, then Jackbox shows their answers.There is Decoy answer.
