So far I've discovered the best way to get likes is the following.
- Get the first post! Most people don't have the attention span to read past the first couple posts especially in threads where its going very fast. If you don't catch the first post your chances of likes are slim.
- Meme posts! Don't worry about creativity when it comes to getting likes, the best way to get likes is by posting an epic memes. Funny dogs, wojacks, the whole deal. The average 4channer has the wit of a 12 year old so seeing these things in unison will create a chemical reaction in his brain that will force him to like!
- Giving people the incentive to like! Let people know that their likes will be put to good use. Phrases along the lines of "Like this post if" will let the 4chan user know that his like will contribute to a greater cause thus earning you more points.
If you combine all these together in one epic post you should find yourself drowning in likes. Good luck out there anon!
