You probably read my opinion about non-sense contests and it looks like this wave has been developed to nonsense posts.
In my examples of non-sense contests you supposed to guess some author thoughts, get answer, upvote and resteem. Now, in non-sense posts you need just upvote and resteem post with body:
"Upvote and resteem this post to get 0.5-2 SBD or Steems"
So now, you even don't need to guess and compete with other contestants: Upvote > Resteem > Get Money
But I'm pretty sure there are a lot of people would do this to get money. So, be prepare to see many-many similar posts in your feed.
but from other hand, this a great point to follow #Steemit users more carefully
